The direct answer: there is a widening chasm between AI-assisted trip planning and AI-completed hotel bookings. Fifty-six percent of travelers have used AI for trip planning (Booking.com survey, 37,000+ respondents, 2026), and 37% use it on travel sites specifically (NYU/BCG, March 2026).

The gap is not a timing problem that will close on its own. It is a structural breakdown in the path from AI recommendation to completed reservation — and hotels that fix it before 2027 will capture bookings their competitors lose to OTAs every time an assistant says “I found a great hotel for you” but sends the traveler to Booking.com to finish. ...

The short answer ChatGPT Ads reached a $1 billion annualized ad revenue run rate within 200 days of launch, is now live in more than 60 countries, and travel has been an allowed advertising category since day one — Expedia was among the very first buyers in the February 2026 US pilot (OpenAI, August 31, 2026; Adweek, February 19, 2026).

Your hotel can be the one ChatGPT names while an OTA pays to sit directly underneath that recommendation, capturing the click on your own inventory. ...
