Expedia just turned on Meta’s Muse and admitted the quiet part about OpenAI ads: it will pay to learn before it knows what the channel costs. That is not strategy. That is how Google Search took the industry hostage the first time.
On the Q3 2026 earnings call, CEO Ariane Gorin told analysts that Expedia’s Muse integration — announced in late September — was going live that same evening. Muse gets Expedia’s prices and content, can recognise travellers, and can either finish the booking inside Muse or hand them to Expedia. In the same breath she said the economics of agentic partnerships with Muse and Google’s AI Overviews are “being worked out.” Expedia is also testing OpenAI’s advertising products and is willing to accept returns that are not as high as mature channels while it figures them out.
Discovery is free. Checkout is the bill
PhocusWire’s Abby Crotty captured the posture cleanly. Gorin framed OpenAI ads as something Expedia must test early, even if the returns lag optimised products. OpenAI’s Sponsored Agents, launched in September, let someone click an ad and start a chat with a business-sponsored agent. That is not a banner. It is a paid conversation sitting between the traveller and your brand.
Skift’s Dennis Schaal asked the right question: will Muse and AI Overviews become the new Google Search? Gorin is hopeful. She pointed to Expedia’s track record of buying customers from big ad and tech platforms at attractive economics. History also shows Expedia spent years complaining about Google’s cost. Hope is not a CAC model.
The numbers around the AI story are still soft. Gorin said agentic AI traffic is high intent but a small share, and it is not denting direct bookings. It is “either incremental, or it’s taken from other paid channels.” Third-party data puts Expedia ahead on US citation share. Then the commercial punchline: agentic AI’s real strength so far is discovery; when people book, they still want a trusted brand that will take care of them if something goes wrong.
Two OTAs. Two scoreboards
Put this next to what Booking said a day earlier. Booking’s own Priceline and Agoda assistants convert at roughly twice the rate of non-users, while LLM referrals stay well under 1% of Booking.com room nights. I covered that in Booking’s AI converts twice as well. Own-assistant conversion is a product. Third-party agentic referral is still a research side-effect — until someone starts charging for the hand-off.
Expedia is betting that when the hand-off gets priced, it will still look like an attractive media buy. Maybe. Or maybe Muse completes the booking inside Muse and Expedia becomes a supplier with a logo on the receipt. Gorin said both paths are open. That should terrify every hotel and airline that thinks “getting cited” equals “getting paid.”
This is the same trap I flagged when Expedia shipped thirty AI features while European travellers asked for proof. Feature theatre and citation leadership feel like progress. Trust and checkout still decide who keeps the margin. Tourism 5.0 is not about prettier agents either — it is about who the traveller’s AI listens to when money moves.
What travel marketers should do this week
Stop treating AI traffic as one line in a dashboard. Split it:
- Own assistant / own app: conversion and booking value. That is Booking’s scoreboard.
- Third-party agents (Muse, ChatGPT, AI Overviews): referral share, hand-off rate, and whether the booking finishes on your domain or inside theirs.
- Paid AI ads / Sponsored Agents: true CAC against brand and Google, including the conversations you fund that never reach checkout.
If you sell through Expedia’s B2B stack, ask a sharper question too. Qantas became the first partner on Expedia’s agentic template in September. Gorin said Expedia can help existing partners — or become the travel engine for an AI company that wants to sell trips itself. That is not a minor product note. It is Expedia saying it will supply whoever owns the agent, including the agent that replaces the OTA brand in the chat.
So here is my take, bluntly: the next distribution war will not be won by the brand with the most citations. It will be won by whoever prices the last mile before Muse, OpenAI and Google finish pricing it for you. Expedia is paying tuition to sit at that table. Hotels and airlines still debating “AI content” are not even in the room.
Are you measuring agent hand-offs — or still celebrating mentions?
