Book a Munich to London flight (didn't finish)
The user asked an AI agent to book a flight from Munich to London; it searched the airline site but couldn't complete the booking.
Done with a custom-built or unnamed agent
- What they did
- The user told an AI agent to book a Munich-to-London flight for the 25th. It found options on Google Flights in about ten seconds, then tried airline and travel sites to complete the purchase, but British Airways, Lufthansa, easyJet, Kayak, Skyscanner, and Expedia all blocked or challenged it; Kiwi’s MCP server was the only route that returned flights and a handoff link for the user to finish entering passenger details.
- How it went
- It never reached the passenger-details page on the normal booking sites, so it did not complete the booking. The only successful step was Kiwi’s MCP server, which returned 15 flights in under four seconds and a link for manual checkout.
- Worth knowing
- The post says no CAPTCHA solving or pretending to be a person was allowed, which appears to be the key constraint that kept the agent from finishing.
