Trip.com
Search and compare flights, hotels, trains and attractions in one chat
Trip.com's app is the one to try when a trip has several legs. Its listing covers one-way, round-trip and multi-city flights, rail journeys in Europe and Asia, hotels in each city, and attractions and tours. That lets you plan a flight into one city, a train to the next and tickets for both in a single conversation, and ask for a train and a flight on the same route to compare them.
Train search is what sets it apart from the Booking.com, Expedia and Tripadvisor apps, whose listings don't mention rail. It suits travelers who already use Trip.com and anyone planning a rail-heavy trip in Europe or Asia.

What you need
- A ChatGPT account. Install Trip.com from the Plugin Directory, then mention it at the start of a message or pick it with
@. See how to install plugins in ChatGPT. - Availability in your region and plan. OpenAI says app availability depends on the app, your plan, region, workspace, role and the ChatGPT surface you use. We couldn't find a Trip.com page that lists supported countries or ChatGPT plans, so check the directory while signed in.
- Admin approval in a work account. In Business, Enterprise and Edu workspaces, admins decide which apps members can use.
The listing is published by Trip.com Group Limited.
Good to know
- Check where the booking happens. The listing mentions booking travel products and 24/7 support in multiple languages, but doesn't spell out whether payment happens in the chat or on Trip.com. Either way, check fare rules, baggage, hotel cancellation terms and ticket conditions on the final booking page.
- Rail coverage is Europe and Asia. The listing doesn't mention trains elsewhere.
- Give it the details up front. Dates, number of travelers and cities produce narrower results than a vague request, and you can refine with follow-ups.
- What the app can see. When connected, ChatGPT may share relevant chats and memories with Trip.com, and apps can see basics such as your IP address and approximate location. Trip.com's terms and privacy policy apply.

Trip.com: common questions
- Is the Trip.com ChatGPT app free?
The listing doesn't mention any fee for connecting the app, and OpenAI makes apps available on free as well as paid ChatGPT plans, subject to region and app. You pay Trip.com for whatever flights, hotels, trains or tickets you book. App use can also count toward your ChatGPT plan's usage limits.
- Can I search trains with Trip.com in ChatGPT?
Yes, for rail journeys across Europe and Asia, according to the listing. Give the departure and arrival cities and a date, for example Paris to Amsterdam next Friday, and ask follow-ups to narrow by time or price. The listing doesn't mention rail outside Europe and Asia, so don't count on it for other regions.
- Can Trip.com plan a multi-city trip in ChatGPT?
It can search the pieces: multi-city flights, hotels in each city, trains between them and attractions at each stop. ChatGPT keeps them in one conversation, so you can change one leg and ask for updated options for the rest. Check each booking's conditions separately before paying.
- What does Trip.com see when I connect it?
ChatGPT may share relevant parts of your chats, and memories if Memory is on, so the app has context for your request. Apps can also see basic details such as your IP address, language and approximate location. Trip.com handles that data under its own terms and privacy policy. You can disconnect it from Settings > Plugins.
