OpenAI acquires travel AI Odessia, which ends its booking service

OpenAI has acquired Odessia, an AI travel service that let people plan and book trips in a conversation. Odessia founder Francis Davidson announced the deal on November 10 and said he would join OpenAI to work on travel. Odessia confirmed the acquisition on its website and said its standalone travel service had closed.

Travelers can email support@odessia.com for changes to existing bookings or to access a travel plan they saved. The company left the address on its website.

Email support for existing bookings

Davidson posted the announcement on X and published the same news on LinkedIn. The X post is timestamped November 10 at 18:00:11 UTC, or November 11 at 03:00:11 in South Korea. Odessia’s website says the service is already unavailable. The notice gives no exact time for the shutdown or for when the notice appeared.

Odessia’s conversation window used to let travelers build an itinerary and carry it through to booking. The website now displays the acquisition notice and the email support channel. The notice specifies changes to existing bookings and access to existing plans. It gives neither a date when support will end nor an expected response time.

A concierge that kept checking

Davidson first introduced Odessia on June 2. OpenAI’s startup team said Davidson and his team used GPT-5.5 and Codex to build it. The initial service brought flights, lodging, activities, itineraries, points and pricing into one conversation. On June 10, Davidson disclosed that the company had raised $6 million in a round led by Sequoia Capital.

On July 9, Davidson said Odessia had begun using GPT-5.6 Sol. He described a trip to Los Angeles as an example. The service looked up flights around a required arrival time, checked cash and points options for the trip and added a flight to the trip, he said. It compared hotels on features he cared about, including fitness facilities, noise and location, and opened a checkout page for the recommended hotel.

On October 14, Davidson introduced a version of the travel concierge available free by text message. He said it could keep checking options in the background and notify travelers as they became available. It could look at different departure dates or reorder the cities in a trip to compare prices. It also looked for flights that travelers could book with points.

The product let people collaborate on the same itinerary. Davidson said travel companions could contribute to a shared plan that Odessia could also work on. He described using previous booking confirmations from a connected Gmail account to learn travelers’ preferences. The shutdown notice does not detail how Odessia will handle account information or data from connected services after the acquisition.

Davidson joins OpenAI to work on travel

Davidson said tens of thousands of early users planned trips with Odessia over the summer, representing more than $60 million in planned travel on an annualized basis. The figure describes travel plans. The announcement gave no separate figure for completed bookings or company revenue.

OpenAI president and co-founder Greg Brockman welcomed Davidson in a reply on X. Davidson did not give a job title or announce a specific product. The public announcements leave the purchase price and terms undisclosed, along with details about whether other Odessia employees are joining OpenAI.

Travel services have appeared in ChatGPT before. When OpenAI introduced apps in ChatGPT in October 2025, Booking.com and Expedia were among its first partners. The apps could show their results in the conversation. OpenAI said that connecting an app for the first time would show users what data might be shared with it. The Odessia announcement did not give a timetable for adding travel features to ChatGPT or say whether existing Odessia users would be able to move their plans to a new service.
