Booking Flights in ChatGPT: The Complete Guide

Adin Flights teamTravel-tech engineers at MoodTrip.AI · · 6 min readChatGPT & AI

You can now book real flights from inside a ChatGPT conversation. No tab switching, no copy-pasting passenger details into a third-party site. The Adin Flights app uses OpenAI's MCP (Model Context Protocol) to plug live airline inventory directly into ChatGPT — and any booking you start in the conversation finishes on a secure checkout page on flights.moodtrip.ai.

What is MCP and why does it matter?

MCP is an open protocol from OpenAI that lets external services expose tools and widgets to ChatGPT in a structured way. Instead of scraping a website, ChatGPT calls a typed API and receives typed results. For travel, that means: a real "search flights" tool with structured offers, instead of "I think Skyscanner has something cheap."

Setting up the Adin Flights app in ChatGPT

  1. Open ChatGPT and go to the apps directory.
  2. Search for Adin Flights.
  3. Click Add. The first time you use it, you'll be asked to authorize access.
  4. Start a new chat and try the example prompts below.

Prompts that work well

"Find me a flight from Tel Aviv to New York around June 15, flexible by 2 days, economy, one adult. I prefer non-stop if it's not more than $200 extra."

ChatGPT will call the Adin Flights search tool, render an inline results card, and let you pick an offer. Click through, complete passenger details, and pay with Stripe — all of that happens on flights.moodtrip.ai with the same offer locked in.

More example prompts

  • "Cheapest flight from London to Tokyo in September, willing to stop over"
  • "Round-trip from JFK to Paris for 2 adults, leaving the second week of October"
  • "Show me my recent bookings on Adin Flights"
  • "What's a fair price for an October flight from Berlin to New York?"

Do I need an account?

No. The booking link that ChatGPT generates supports guest checkout — your email is enough for the confirmation and e-ticket. If you sign in, your bookings appear under /bookings for easy access.

Why this is better than a normal search

  • Natural language. Describe the trip; skip the forms.
  • Reasoning. ChatGPT can compare options, flag risks ("only 30 min connection"), and explain trade-offs.
  • One-step booking. The conversation generates a verified booking link — no re-entering data.
  • Auditable. Every tool call is visible — you see exactly what the AI searched.
