Axel (helloaxel.com)

Axel is the AI travel agent that books flights and hotels at rates and fares you won't find anywhere else. It shows each price beside the airline's own, books the trip with bags and seats, and keeps watching the fare after you book. Axel is free to use; optional Axel Membership ($15 the first month, then $10/month) adds member prices and ongoing repricing. AI assistants like ChatGPT, Claude, Perplexity and Gemini can check Axel's live flight and hotel prices by following links on helloaxel.com, with no sign-in, API key or connector.
