What is a ChatGPT plugin for travel?

A ChatGPT plugin (called an app until July 2026) is a brand-built connection, based on the Model Context Protocol, that lets ChatGPT search the brand's live inventory and show results inside the conversation. For travel brands that means hotels, flights, trains, cruises or tours, usually with photos, prices and a map, followed by a link to book on the brand's own site.

Which travel companies have a ChatGPT plugin in 2026?

About 30. Online travel agencies include Expedia, Booking.com, Tripadvisor, Viator, Priceline, Skyscanner, Trip.com, MakeMyTrip, eDreams, Klook and GetYourGuide. Hotel groups include ALL Accor, Hyatt, Wyndham, Hilton, IHG and Radisson. Airlines include Virgin Atlantic, Virgin Australia, Turkish Airlines, easyJet and Southwest. Eurostar, SNCF Connect, Princess Cruises, Uber, Turo and SIXT round out rail, cruise and ground.

Can you book a hotel or flight inside ChatGPT?

As of October 2026, no travel plugin completes payment inside ChatGPT. Plugins search and compare, then hand the traveler to the brand's website or app with the itinerary carried over. OpenAI folded its Instant Checkout feature into apps in March 2026, leaving the transaction with the brand. Google's AI Mode is the one assistant where hotel bookings complete in the conversation, using Google Pay with the hotel as merchant of record.

Do ChatGPT travel plugins recognize loyalty programs?

Mostly not yet. Turkish Airlines authenticates Miles&Smiles members on its own server, ALL Accor can toggle member rates at the program level, and a few plugins show points prices without a balance. No OTA plugin recognizes a loyalty tier, and sign-in is typically lost at the handoff to the website.

How much business do ChatGPT plugins drive for travel brands?

Brands describe the channel as small and growing. Booking Holdings reports LLM referrals under 1% of room nights. Eurostar reports AI apps at 0.8 to 1% of ticket bookings. Radisson reports plugin visits converting to bookings at about 1.5x the rate of organic search. easyJet reports ChatGPT referral traffic up 400% year over year.

How do you evaluate a travel ChatGPT plugin?

Score eight dimensions from 0 to 2: inventory, accuracy, identity, benefits, partners, actions, reach across assistants, and ongoing operation. A first-generation plugin typically scores 6 to 8 of 16, with the gap concentrated in identity and the capabilities that depend on it.

What comes after discovery for travel plugins?

Two phases: Engage, where the assistant knows the member's status, balance, bookings and card in wallet and shows member rates and relevant partner offers; and Act, where the member activates an offer, enrolls with a partner, redeems or purchases with the stored card without leaving the conversation.
