Delta's AI Pricing: The Two Sentences That Don't Match

Eric Marketts

Delta's president stood at an investor day and described the destination as offer management. A price available on that flight, at that time, to you, the individual. Delta's lawyers later told the United States Senate there is no fare product Delta has ever used, is testing or plans to use that targets customers with individualized prices based on personal data.

Steph Nell

Both of those are real, from the same company. And here is the thing most people reading them miss. They do not actually contradict each other. One says offer. One says price. And whether that distinction is a real defence or a piece of wordplay is the most consequential unanswered question in airline retailing right now.

Eric Marketts

So which sentence is true?

Steph Nell

Probably both. And that is worse, not better. One is engineering, one is legal, and this industry has never written the sentence that tells you where one ends and the other begins.

Eric Marketts

Welcome back to The V1 Airline Retailing Report. I'm Eric Marketts.

Steph Nell

And I'm Steph Nell. Last week we ended on who actually holds the thing. This week the question is narrower and harder. Who wrote the terms? Because three stories this week sit at three different chokepoints in airline retailing, and at every one of them, the terms that govern it have not been written down by anybody.

Eric Marketts

For anyone new, here is what we do. Every Monday we take the developments that actually move airline and travel distribution, and run each through the bull case, the bear case, and the critical take. Not the press release. The strategic read. Sources are in the episode details.

Eric Marketts

Narrative one. Congress asked eight airlines how their artificial intelligence sets your fare. Delta's whole defence rests on the difference between an offer and a price, and this industry has never defined it.

Steph Nell

Narrative two. A startup, a G-D-S and a payments company built the thing OpenAI could not ship. Look at which of the three is replaceable.

Eric Marketts

Narrative three. When a machine finishes the sale, nobody has said who gets paid. And the platforms are walking away from the commission on purpose.

Steph Nell

And here is the through-line. For fifteen years this industry has been making the offer contestable. It is succeeding. And as it succeeds, the value drains out of the offer and pools at the three places the standard never reached. The logic that prices the offer. The rail that fulfils it. And the money that changes hands when a machine, not a person, completes the purchase. Nobody has published terms at any of the three.

Eric Marketts

Let's get into it.

Eric Marketts

Before the news, we have to separate three things that the press calls by one name, because this entire story is people using the same phrase to mean different things.

Steph Nell

The phrase is dynamic pricing, and it covers at least three practices that are not the same. Start with the oldest. Revenue management. Forty years old, every airline on earth runs it. The price of a seat moves with the flight, the date, how full the cabin is, how many days until departure, and which fare bucket still has inventory in it. Two people can pay different amounts for identical seats, and they always have. Nobody has ever called that surveillance.

Eric Marketts

Second one.

Steph Nell

Continuous or dynamic pricing. Instead of pulling a price out of a set of pre-filed fare buckets, the system computes a number in real time. Newer, more granular, and increasingly what the modern retailing stack is built to do. But notice what the input still is. The flight. The date. The demand. It is a better answer to the same question.

Eric Marketts

And the third.

Steph Nell

Individualized pricing. The price varies according to who is asking. Your income, your browsing history, your device, your location, what the system believes you will tolerate before you walk away. That is a different question entirely, and it is the only one of the three that is actually contested.

Eric Marketts

And there is a fourth phrase, which is the one Congress actually uses.

Steph Nell

Surveillance pricing. Hold onto this, because it comes back at the end of the story. It has no agreed definition. Not in statute, not in regulation, not in any industry document we could find. It is a political term, and it points roughly at that third practice — a price set from what a company knows about you personally. Roughly. And when a phrase with no fixed meaning starts turning up in Congressional letters, class-action captions and trade-body testimony, everyone is arguing hard about a word nobody has pinned down.

Steph Nell

The test is the input, and I would put it even more simply. Is the price a fact about the flight, or a fact about the person? Everything in this story turns on that line, and almost nobody in this industry has drawn it out loud.

Eric Marketts

One more term, and it is the one this whole show is built on.

Steph Nell

Offer management. Regular listeners know it. In the Offer and Order world this show tracks every week, an airline stops publishing a static grid of fares and instead constructs an offer in response to a specific shopping request. That is the architecture. That is what Offer and Order is for. And I want people to sit with the uncomfortable part, because it arrives later in this story. An offer built in response to a specific request is, by design, more specific than a published fare. The industry has spent a decade selling that as the whole point.

Eric Marketts

And an offer is not only a price.

Steph Nell

That is the crux of this entire narrative, so hold onto it. An offer is a bundle. Fare, bag, seat, boarding, whatever the airline assembles for that request. The price is one component inside it. So it is perfectly coherent to build a personalised offer, different contents for different travellers, and still charge everyone the same underlying fare. Coherent, and legally very different. Whether that distinction survives contact with a regulator is the open question, and nobody in this industry has tested it in public.

Eric Marketts

That's the setup. Here's what happened.

Eric Marketts

On August eleventh, Representative Frank Pallone, the ranking member of the House Energy and Commerce Committee, sent letters to eight airlines. American, Delta, United, Alaska, JetBlue, Southwest, Frontier and Hawaiian. Nineteen numbered questions each, answers requested by August twenty-fifth. How often the systems adjust prices. Which categories of consumer data carry the most weight. Whether income, browsing history or location factor in. Whether a human reviews what the algorithm produces. Whether third-party data brokers are involved, and whether pricing segments on income, sex, age or race.

Steph Nell

Now three things about the instrument, because almost every write-up of this overstated it. Pallone is the ranking member, the senior member of the minority. It is a letter, not a subpoena, it carries no enforcement power, and it is not a formal committee investigation. Second, it is not new and it is not about airlines. Pallone sent the same letter to twenty-five major corporations in May. The airlines are an expansion of an existing inquiry. And third, read the questions and you can see the template. Two of the nineteen are about tariffs and repricing after the Supreme Court's February decision. That is not an airline question, and it tells you how airline-specific this document actually is.

Eric Marketts

And as we go to air?

Steph Nell

We could not find any public reporting on what any of the eight filed by the deadline. So we are reading the question, not the answers.

Eric Marketts

Then give me Delta's position.

Steph Nell

Delta says it does not share customer personal information with Fetcherr, the A-I pricing company it works with, and that pricing runs on aggregated route and flight data with human oversight. And it has said a version of this before. July thirty-first, 2025, Delta's chief external affairs officer wrote to three senators. The sentence everyone quotes is this one, and I am going to read it exactly, because the exact words are the whole story. Quote, there is no fare product Delta has ever used, is testing or plans to use that targets customers with individualized prices based on personal data.

Eric Marketts

Read that again, slower.

Steph Nell

INDIVIDUALIZED PRICES. Based on PERSONAL DATA. Two qualifiers, and they are doing enormous work. That sentence does not say Delta will never build you a personalised offer. It says the price inside it is not set from your personal data. Those are different claims, and the second one is far narrower and far more defensible than the way it gets quoted.

Eric Marketts

Now put it next to the investor day.

Steph Nell

November 2024. Glen Hauenstein, THEN Delta's president, describing where this goes. I am going to paraphrase rather than quote, and I want to explain why. There are at least three published renderings of what he said that afternoon and they differ in their wording. We have not seen the transcript. What every version agrees on is the shape. It gets melded together into what he called offer management, and the destination is a price available on that flight, at that time, to you, the individual.

Eric Marketts

He said offer management. Our phrase.

Steph Nell

He said offer management, and that is why this story belongs on this show rather than on the evening news. The president of the largest airline in the world described the destination in the exact vocabulary the retailing industry has been selling to airline boards for a decade. And notice what he did with it. He used offer and price in the same breath as though they were the same thing. That is not sloppiness on his part. That is how this entire industry talks. And it is precisely the omission Delta's lawyers now need to un-do.

Eric Marketts

Is he still there?

Steph Nell

He retired in February. Which changes nothing, because two dozen members of Congress quoted him back at Delta in a letter in November of last year, and this August's letter is the third round.

Eric Marketts

Third round?

Steph Nell

Senators in July 2025. Twenty-four House members that November, quoting Hauenstein directly. Eight airlines including Delta this August. So the framing that Delta just got a letter is wrong. Delta has been answering this question for over a year, and its answer has not moved.

Eric Marketts

And the money.

Steph Nell

Careful here, because this is the figure most likely to get mangled. Ed Bastian said in the last two weeks that A-I could take Delta from around a ten percent margin to around fifteen, his words, a fifty percent improvement in your profitability. But read what he actually attributed it to. Cost. Maintenance, crew, fuel, taking two to four points out of the cost base through better decisions across the whole airline. That is not a pricing claim. He named revenue decisions in the same breath, and he named all of it while the pricing questions were live, which is its own kind of choice. But if you quote fifty percent as an A-I pricing number, you are quoting it wrong.

Eric Marketts

How much of Delta's pricing is actually A-I today?

Steph Nell

Same discipline. The number everyone repeats is three percent. That is from the second quarter of 2025, it referred to domestic fares specifically, and Delta's stated goal at the time was twenty percent by the end of that year. We could not find a published current figure for 2026, and the coverage from this month is still recycling the 2025 number. So anybody telling you Delta prices three percent of tickets with A-I today is quoting something more than a year old that was never about the whole network.

Eric Marketts

Bull case.

Steph Nell

The bull case is that Delta is probably telling the truth, and the distinction it is drawing is a real one. If the inputs are route, flight, date and demand, this is revenue management at higher resolution, which airlines have run since deregulation without anybody calling it surveillance. Human review sits on top. And the offer-versus-price line is not a lawyer's trick, it is how the architecture actually works. You can assemble a different bundle for different travellers and still price the underlying fare identically for everyone. That is a coherent product design and a coherent legal position at the same time.

Eric Marketts

Bear case.

Steph Nell

The bear case is that a distinction nobody has ever explained in public is not a defence, it is a liability. Delta is asking Congress, and eventually a court, to hold apart two words that this entire industry has spent a decade using interchangeably, including Delta's own president on a stage. And it is not hypothetical any more. JetBlue has been defending a surveillance-pricing class action since April, filed in the Eastern District of New York, alleging it set prices from inferred willingness to pay. JetBlue is on Pallone's list too. So the sequence is already running: letter, then suit, then discovery, and discovery does not care what you meant.

Eric Marketts

Critical take.

Steph Nell

The critical take is that this industry built a vocabulary that cannot survive a Congressional letter, and it knows it, because it already tried to fix it and only got halfway. Here is the part almost nobody connected. In June, Airlines for America's chief executive Chris Sununu sat in front of House Judiciary and said he would back banning surveillance pricing outright. One hundred percent, his words, and that no member airline does it. That is the trade body drawing exactly this line, on the record, two months before these letters went out. So the industry did show up. What it did not do is define the term it volunteered to be banned from. It endorsed a prohibition on a practice nobody has specified, while every vendor deck and every board pack still promises personalization and individualized offers as the whole justification for Offer and Order spending. That is the gap. Not between Delta and Congress, but between what this industry sells internally and what it is willing to defend externally. The architecture makes a per-request offer true by design. A per-person price is a separate choice. If you never separated them in your own marketing, you are now asking a regulator to separate them for you, and regulators draw lines with much blunter instruments than we would.

Eric Marketts

Monday morning?

Steph Nell

Two things, and they are both language, not technology. First, run a search on your own public material. Investor decks, sales collateral, your retailing vendor's website, anything with your logo on it. Every instance of personalized, individualized, tailored to the traveler. Read those sentences the way a Congressional staffer would, and specifically ask whether they say offer or price, because Delta's entire position rests on that word. Second, and this is the harder one, ask whether your commercial leadership and your general counsel can state the line between offer-level and person-level pricing in one sentence, and give the same sentence. If they cannot, that is not a Delta problem you might get someday. Your trade body already promised a regulator that you do not do the thing nobody has defined.

Eric Marketts

Second narrative, and it closes a loop we opened back in episode four. Set up what an agentic booking actually needs, because the word gets thrown around loosely.

Steph Nell

An A-I agent that books travel has to do three separable things, and the industry keeps talking about them as one. First, discovery. Understand what you want, compare options, make a recommendation. That is the part everybody has demonstrated, and it is the easy part. Second, transaction. Actually hold the inventory, confirm it, and get a real booking reference back from a system of record. Third, money. Take the payment, and be answerable for it afterwards.

Eric Marketts

And the second one is where everything dies.

Steph Nell

The second one is where everything dies, because it requires governed, authenticated access to real inventory. A model cannot guess a booking into existence. Somebody has to have built an interface that a machine can call, that the airline or the aggregator will honour, and that produces a record the traveller can actually show at an airport. That is not a model problem. It is an infrastructure problem, and it has to have been solved before the agent shows up.

Eric Marketts

Which is the OpenAI story.

Steph Nell

Which is the OpenAI story, and I want to state it precisely, because the shorthand version everybody uses is wrong. In March, OpenAI pulled native checkout out of ChatGPT's main interface and pushed payment back to merchants. That was retail commerce, settled through Shopify. Travel never got that far. Expedia and Booking were apps inside ChatGPT that always handed you off to their own site to complete the booking. So it is not that OpenAI stopped closing flight bookings. It is that the largest consumer A-I audience on the planet has never once closed one. Not because the model was not good enough. Because the plumbing underneath it was never there.

Eric Marketts

That's the setup. Here's what happened.

Eric Marketts

Mindtrip, a travel planning startup, launched on May sixth what its partners describe as travel's first all-in-one agentic A-I flight booking experience. Search, compare and pay for a flight inside the conversation. The partnership was announced in February and runs on two pieces of somebody else's infrastructure. Sabre Mosaic, and specifically what Sabre calls its agentic-ready air A-P-Is, supplies the inventory and the booking. PayPal supplies checkout inside the chat, including Buy Now Pay Later.

Steph Nell

Two notes on the claim before we analyse it. Travel's first is their phrase, from Sabre's and PayPal's own announcements, and we are attributing it rather than endorsing it. And on Mindtrip's size, the widely repeated figure is a fourteen-person company. We could not verify that. What we could verify is that TechCrunch covered Mindtrip's launch in 2023 with a twelve-person founding team, which is remarkable enough and has the advantage of being sourced.

Eric Marketts

Who said what?

Steph Nell

Garry Wiseman, Sabre's president of product and engineering, says for the first time we've truly bridged the gap between inspiration and purchase, allowing travelers to move from intent to transaction entirely within the same chat, rather than simply being redirected to book on a website. Worth reading the second half of that sentence, because it is much narrower than the first half and it is the part that is actually checkable. And Mindtrip's chief executive, Andy Moss, frames it as travel shifting from search to A-I-assisted decision-making. Both are participants describing their own product, so weight them accordingly.

Eric Marketts

Now look at the stack.

Steph Nell

Look at the stack, because the stack is the story. Mindtrip owns the conversation. Sabre owns the inventory and the booking rail. PayPal owns the money. And the airline. The airline is content. It is a ROW in Sabre's feed, priced against every other row, and it set not one term of how the machine buys from it.

Eric Marketts

Bull case.

Steph Nell

The bull case is that this is the real architecture of agentic travel, and it arrived roughly on schedule. Not one company doing everything. A stack. A conversation layer, an inventory and booking layer, a payment layer, each of them licensed rather than built. That is genuinely how this gets constructed, and it means the barrier to a working agentic booking just fell to whoever can strike two partnerships. That is a dramatically lower bar than building the whole thing, and it should mean more of these, faster.

Eric Marketts

Bear case.

Steph Nell

The bear case is that a launch is not adoption and we have no volume. One startup, one announcement, and a points promotion attached to drive first use, which tells you they expect trial to need a nudge. Nobody has published how many flights have actually been booked this way. And the hard part of travel was never getting to the word buy. It is the change, the cancellation, the schedule move, the irregular operation at eleven at night. None of that has been demonstrated inside a chat window, and the complexity that made OpenAI retreat did not go away because the checkout got smoother.

Eric Marketts

Critical take.

Steph Nell

The critical take is that the booking rail did not go to the company with the biggest audience. It went to the company a machine could safely call. Sabre did not win a piece of the agentic era by having better artificial intelligence than OpenAI. It won it by having already built governed, authenticated, transactable access to real inventory before anyone showed up wanting to use it. That is an unglamorous, decades-in-the-making asset, and in this stack it is the scarce one. Now grade the pieces. Mindtrip owns the conversation and is the most replaceable component in the diagram, because any competent model can be swapped in tomorrow. PayPal is substitutable with real effort. Sabre is not, at least not quickly. And the airline is the most interchangeable piece of all, because it is content and it is priced against its neighbours in a feed it does not control. That is airline invisibility, the thing we warned about in episode four: the carrier present in the transaction but invisible to the buyer. It has stopped being a forecast.

Eric Marketts

And the standing watch item.

Steph Nell

Sixth episode running. We keep asking whether any airline has published terms for a machine buyer. Authentication, rate limits, a price for the query. Rate limits we corrected two episodes ago, because Lufthansa's terms have carried a look-to-book cap since 2023 and we were wrong to say nobody had one. Authentication and a published price for the query, we still cannot find at any carrier. And this week the argument for publishing them got sharper, because a machine is now completing purchases through an intermediary's rail rather than a carrier's.

Eric Marketts

Monday morning?

Steph Nell

Go find out whether your content is inside Sabre Mosaic's agentic air A-P-Is, and on what commercial terms, because if a machine books you this month it is booking you through that pipe and not through your website. And then ask the harder version. If an agent queried you directly instead, what would it find, what would it have to prove to get in, and what would the query cost. If you cannot answer those three, you are CONTENT.

Eric Marketts

Last narrative, and it needs two definitions that sound like accounting and are actually about power.

Steph Nell

First, merchant of record. Whoever is the merchant of record is legally the seller. They take the payment, they hold the customer's payment relationship, and they own what comes after it. Chargebacks. Refunds. Fraud liability. Regulatory exposure. It is not a billing detail, it is who is answerable when the transaction goes wrong.

Eric Marketts

And commission.

Steph Nell

Commission is who gets paid for producing the sale. In the world we all grew up in, an agency or an O-T-A sells a seat and receives some economics for having done it. And here is the thing worth holding. In the O-T-A era, both of those questions got answered. Not by a standard, and not quickly. By twenty years of bilateral contracts, litigation and a great deal of airline money spent buying back its own customers.

Eric Marketts

So both questions are settled in the old channel.

Steph Nell

Settled, and expensively. Which is why it matters that in the new one, neither of them has been answered at all.

Eric Marketts

That's the setup. Here's what happened.

Eric Marketts

The plumbing for agentic commerce shipped. OpenAI and Stripe published the Agentic Commerce Protocol in September of 2025. Google has its own agent payments work and announced a Universal Commerce Protocol in January. So the technical means for a machine to complete a purchase exist and are open.

Steph Nell

And the commercial question underneath them is untouched. When an agent completes the booking, who is owed a commission, and who is the merchant of record? Watch the direction of travel, because it is the tell. In March, OpenAI pushed native checkout back out to merchants, and Expedia and Booking shares both rose on the news, which tells you how the market read it. Neither OpenAI nor Google appears to want to be the merchant of record. They would rather the partner handle payment and keep its usual economics.

Eric Marketts

That sounds like good news for suppliers.

Steph Nell

It sounds like good news. Now look at where the money went instead. ChatGPT advertising launched in February. Best Buy and Enterprise Mobility confirmed they were in the pilot. Expedia is named as an early advertiser in trade coverage, though Expedia itself has not confirmed it, so treat that one as reported and not established. But the shape is unmistakable, and it does not depend on which travel brand bought first. The platform declined the transaction and took the attention.

Eric Marketts

Bull case.

Steph Nell

The bull case is that this is the opening airlines have wanted for twenty years. If the platform refuses to be merchant of record and hands the payment back, then the supplier keeps the transaction, keeps the payment data, keeps the servicing relationship and keeps the customer record. That is disintermediation running backwards for the first time in the history of this business. An airline with a clean, agent-ready offer A-P-I can let somebody else do the discovery and still own everything that matters after the click.

Eric Marketts

Bear case.

Steph Nell

The bear case is that we have watched this movie and we know how it ends. The last time distribution economics were unresolved, the O-T-As resolved them, in their own favour, and airlines spent two decades and an enormous amount of capital buying back access to their own demand. If the value migrates into in-chat advertising, the airline is paying a new intermediary for access to customers it used to reach directly. That is not the absence of a toll. It is a toll that moved from a booking fee to an ad auction, and an ad auction is harder to see, harder to benchmark and much harder to leave.

Eric Marketts

Critical take.

Steph Nell

The critical take is that everybody is asking who gets the commission and it is the wrong question. The commission is the old model, and the platforms are visibly declining it. That is not an oversight, it is a choice, and it is a rational one. Merchant of record is liability without leverage. Why accept chargebacks, refunds and regulatory exposure on a two hundred dollar airfare when you can sell the placement that determined which airfare got recommended in the first place? So the real fight is not for the transaction. It is for the conversation, and it monetises through attention rather than through sales. And that is a categorically worse position for airlines than the O-T-A era ever was, for four specific reasons. An ad auction has no IATA. It has no standard. It has no settlement rail an airline can audit. And it has no requirement to ever publish a take rate. Every one of those existed, eventually, in the channel airlines complain about. This industry spent a decade building Offer and Order to finally own the offer. It is on course to hand the thing that comes before the offer, the sentence the customer typed describing what they actually want, to a layer with no published economics whatsoever. Owning the order does not help you if somebody else owns the intent.

Eric Marketts

Monday morning?

Steph Nell

Ask who inside your organisation owns the agent channel commercially, not technically. Not who is building the A-P-I. Who decides what an agent-originated booking is worth, what you would pay for placement, and whether you will be merchant of record on it. In most airlines that person does not exist, and the seat is being filled by whoever writes the terms first. Right now that is not going to be you.

Eric Marketts

Here's the spine.

Steph Nell

Three chokepoints, and unwritten terms at every one. Delta's whole defence rests on a distinction between offer and price that this industry has spent a decade refusing to draw, and it is now being drawn for us, in a hearing room. The agentic booking rail got written by a G-D-S and a payments company while airlines were CONTENT in the feed. And the commission and merchant-of-record question for machine-completed sales is being answered right now, by silence, in favour of an advertising auction. In all three, the party writing the terms is not the airline.

Eric Marketts

So what is the rule.

Steph Nell

The offer stopped being the prize. We spent fifteen years making it contestable and we succeeded, and value does not evaporate when something gets commoditised, it relocates. It went to the logic that constructs the offer, the rail that fulfils it, and the economics of who gets paid when a machine finishes the sale. Those three places have one thing in common. Nobody has published rules for any of them. And an unwritten rule is not a neutral space. It is a space somebody else is going to fill.

Eric Marketts

And the sharper version, for the people who have been here a while.

Steph Nell

The sharper version is that this industry is very good at building things and very bad at defining them. We built individualized offer construction and never defined the line between an offer for a request and a price for a person, and then our own trade body went in front of Congress and offered to be banned from a practice nobody had specified. We built machine-readable retailing and never defined what a machine has to prove to use it, so an intermediary defined it instead. Same failure both times. The engineering shipped and the definitions never did.

Eric Marketts

And the metric.

Steph Nell

Two. First, new this week, and it costs nothing. Can your commercial lead and your general counsel state the line between offer-level and person-level pricing in one sentence, and is it the same sentence? Second, the standing ask, graded a sixth time. Authentication, and a price for the query. Rate limits we withdrew two episodes ago and we are not re-asserting them. On authentication and pricing for machine access, we still cannot find a carrier that has published either.

Eric Marketts

If you own a channel P and L, send this to whoever writes your public retailing language. Not to agree with us. To have them read it out loud in the voice of someone who is looking for a contradiction.

Steph Nell

And the standing ask, unchanged. If you are a carrier about to publish real terms for a machine buyer, on authentication, on pricing, or on commission, we want to hear from you. The first one to write the terms is the only one who gets to write them.

Eric Marketts

Send us the correction too, if we got something wrong. We read them, and we read them on air.

Eric Marketts

We'll be back next Monday. I'm Eric Marketts.

Steph Nell

I'm Steph Nell. Thanks for listening.

Eric Marketts

Write the terms before somebody writes them for you. Stay sharp out there.
