Why OTAs Might Keep Winning Against AI Agents

OTAs might keep winning because they hold the inventory, reviews and ad budgets that AI agents depend on, and they are already paying for placement inside ChatGPT and Google. In August 2026 Booking said AI traffic was "significantly below 1%" of its room nights. So far agents look like a new OTA acquisition channel more than a replacement.

This page makes the strongest case I can for the OTAs, because the evidence for it is good. Every source was read on October 8, 2026. For the opposite case, see Will AI Agents Replace Booking.com?.

How much business do AI agents send OTAs today?

AI agents send OTAs very little business so far. Booking Holdings CFO Ewout Steenbergen said on August 4, 2026 that traffic from large language models, paid and unpaid, was "significantly below 1% of our room nights," with no material change over recent quarters (Q2 2026 call, Investing.com). Expedia CEO Ariane Gorin said "agentic traffic remains small" (Q2 2026 call, The Motley Fool).

A small channel can grow fast, so the share alone does not settle the question. The share does show that the OTAs have time. They get to see agent behavior in their own data and adjust before agents carry real volume.

Why do AI agents still need OTA inventory?

AI agents need live rates and availability for millions of properties, and OTAs already have them in one place. Booking Holdings listed about 4.4 million properties at the end of 2025, including about 500,000 hotels, motels and resorts (Booking Holdings 10-K). Expedia listed about 3.6 million lodging properties (Expedia Group 10-K).

Agents already lean on that supply. Meta's Muse books flights through Duffel, but for hotels it opens a browser and shops consumer sites such as Expedia and Hotels.com (Skift, September 9, 2026). In Skift's October spot tests, Muse failed at the room-and-rate step on Hilton, Marriott and Hyatt sites. Skift summarized BTIG analyst Jake Fuller's view that agents are more likely to become a customer acquisition channel for OTAs than a threat, because OTA inventory and pricing data is faster to use than crawling hotel sites one by one (Skift, October 2, 2026).

Are OTAs paying to show up inside AI assistants?

Booking and Expedia are both paying for placement inside AI assistants. Steenbergen said Booking is "part of the test group of OpenAI for CPC," a paid placement program. Gorin said Expedia was "an early adopter of ChatGPT's latest ad product." Google's Direct Offers pilot, which shows paid travel offers during AI-assisted trip planning, started with Booking Holdings and Expedia and later added IHG (Skift, July 28, 2026). Booking.com, Expedia, Hotels.com, Priceline and Trip.com are also launch partners for hotel booking in Google AI Mode (Skift, August 27, 2026).

The budgets behind that are large. Booking Holdings spent $8.19 billion on marketing in 2025, about 30% of its $26.9 billion revenue (10-K). Expedia's direct selling and marketing cost $7.35 billion, 49.9% of revenue (10-K). An assistant that sells ads has a reason to keep advertisers of that size in its answers. Citrini Research makes a similar point about Meta, arguing it may prefer to partner with intermediaries given how much Booking spends on advertising (Citrini Research, Agentic Reality).

Why did OpenAI move ChatGPT checkout to apps?

OpenAI moved ChatGPT purchases into partner apps in March 2026 after people researched products in the chat but did not buy there. An OpenAI spokesperson said "instant checkout is moving to apps, where purchases can happen more seamlessly," and Retail Systems noted that Expedia and Booking.com had already built apps for purchasing through ChatGPT (Retail Systems, March 2026).

For travel, that kept the OTA app in the transaction. Skift headlined the change as "Good News for Expedia and Booking" and wrote that investors in both companies were "breathing a sigh of relief." An OpenAI spokesperson told Skift the Agentic Commerce Protocol would serve "as the infrastructure that connects users to merchants across the full shopping journey" (Skift, March 5, 2026).

Do travelers still trust OTA brands over AI agents?

Booking expects brand trust to matter more as agents spread. CEO Glenn Fogel said on the Q2 2026 call that as travelers start trips in AI tools, "trusted brands will play an even more important role in where they ultimately choose to book" (Investing.com transcript). Booking's own numbers fit that view. Consumers who came straight to Booking's platforms booked a "mid-fifties percentage" of its room nights in 2025, and its mobile apps also handled a mid-fifties share (Booking Holdings 10-K). On the same call Steenbergen said the B2C direct mix "remained stable in the mid-60% range" (Investing.com transcript).

A traveler who opens the Booking.com app out of habit never passes through an agent. Citrini puts the opposite view well: "Machines have no habits, and aren't influenced by ads."

Will booking through an AI agent be commission-free for hotels?

Booking through an AI agent will probably not be free for hotels. Hilton CIO Michael Leidinger, who thinks agents put OTAs "under real threat," also expects personal agents to become commissionable channels, and Skift reports Meta has said it will eventually charge for transactions through Muse (Skift, September 29, 2026). Leidinger also expects agents to keep re-shopping a booking until departure, which means more searches per booking for hotel systems to carry.

If an agent charges a fee and still finds the room on an OTA, the hotel can end up paying twice. The cost comparison depends on fees no agent platform has published. I go through the math in OTA commission vs AI agent bookings.

Do parity rules and contracts still protect OTAs?

Parity rules protect OTAs less in Europe than they used to, but contracts and platform practices still shape what a hotel can do. Booking's 10-K says Booking.com changed its terms to address the Digital Markets Act ban on parity arrangements in the European Economic Area, and records commitments to regulators on parity. Marriott's agreements with intermediaries generally run two to three years (Hospitality.today).

Hotels also report less control over their own rates. In HOTREC's 2026 study, 51% of European hotels reported OTAs selling their rooms below the hotel's own price at least occasionally, and 44% reported OTA multi-sourcing, where rates or inventory appear through other platforms (HOTREC executive summary, PDF). An agent comparing prices may find the OTA rate lower than the hotel's.

What could still break the OTA position?

The OTAs' own filings list what could break their position. Booking's 10-K says "AI agents may further evolve into full-service booking platforms, increasing competitive pressure and disintermediating" online travel companies. Expedia's says "Any failure to effectively navigate this 'agentic' revolution could have a material adverse effect." If the big chains give agents their rates through Google AI Mode and ChatGPT apps, and agents learn to finish bookings on brand sites, travelers searching for chain hotels would need the OTA less.

That shift would land on chains first. Hilton says "80% plus" of its business is already direct (Q1 2026 call). Independent hotels have no comparable route. OTAs supplied 63.4% of their 2025 bookings in Cloudbeds' data (Cloudbeds). The full channel figures are in OTA vs Direct Hotel Bookings in 2026.

What does this mean for independent hotels and rental operators?

For independent hotels and rental operators, my read of the evidence is that more guests will arrive in 2026 through OTAs that an agent picked. The OTA keeps its commission and the agent may add a fee, while the property still answers the guest's questions, handles changes and runs the stay.

That part is where Conduit works. We build AI agents that answer guest messages and calls across OTA inboxes, SMS, WhatsApp and phone, and guest portals for upsells and guidebooks. Conduit does not take bookings or replace an OTA. If you are choosing a tool for the guest conversation, our ranked list of guest communication platforms shows how we score them.

FAQ

OTAs report their exposure to AI agents in annual filings and quarterly earnings calls, so the answers below quote those documents and dated trade press. Every source is listed at the end of this page and was read on October 8, 2026, and the agent figures change each quarter.

Are OTAs dying because of AI?

OTAs are not dying because of AI so far. Booking said in August 2026 that AI traffic was "significantly below 1%" of room nights, Booking grew gross bookings 12% in 2025, Expedia grew them 12% in the second quarter of 2026, and both are buying placement inside ChatGPT and Google.

Why would AI agents use Booking.com or Expedia?

AI agents use Booking.com and Expedia because those sites have live rates for millions of properties in one place. Booking listed about 4.4 million properties at the end of 2025, and Meta's Muse shops sites such as Expedia and Hotels.com when it books hotels.

Are Booking.com and Expedia advertising inside ChatGPT?

Booking.com and Expedia both pay for visibility in AI assistants. Booking is in OpenAI's CPC test group, Expedia was an early adopter of ChatGPT's ad product, and both were in Google's Direct Offers pilot before IHG joined.

Did OpenAI stop letting people book inside ChatGPT?

OpenAI moved checkout from ChatGPT itself into partner apps in March 2026. Booking.com and Expedia already had apps in ChatGPT, so travel purchases now finish inside those apps.

Will hotels pay commission to AI agents?

Hotels will probably pay something to AI agents. Hilton's CIO expects personal agents to become commissionable channels, and Meta has said it will eventually charge for Muse transactions. No agent platform has published a hotel fee yet.

What is rate parity and does it still apply?

Rate parity is a contract term that stops a hotel from selling cheaper elsewhere than on an OTA. In the European Economic Area the Digital Markets Act bans parity arrangements for Booking.com, but contracts and OTA undercutting, reported by 51% of European hotels to HOTREC, still affect pricing.
