What an AI travel agent actually does, and how to pick one

Most AI travel tools can plan trips but cannot complete bookings due to lack of real-time inventory access, with a 2026 review finding that 15 platforms showed pricing changes at checkout. Navan Edge differentiates itself by booking flights, hotels, and restaurants through real-time systems without redirects, while offering preference memory and human support, addressing the fact that only 2% of travelers currently trust AI to book trips independently.
