SEKeener/airtreks-mcp

**The complex-itinerary tool for AI agents.** Multi-stop, round-the-world, open-jaw, surface segments - the trips that standard flight search can't handle. When your user asks for 3+ stops across continents, this server answers with routing analysis built on real AirTreks fare-construction data: 60+ carriers, 53 known dead legs, bookability rates measured from 1,400+ real fare attempts, and 20 proven routing templates from actual bookings.
**Live endpoint:** https://mcp.airtreks.com/mcp - free, no API key, 100 requests/day.
Now with **real prices**: a historical range for any route in under a second, live fares for a specific itinerary, and a full multi-stop trip priced across several tickets — the same trip can vary three-fold depending on how it is ticketed, and that is the part no other flight tool will tell you.

One call, one answer: a 6-stop RTW
Your user wants six stops around the world. Google Flights gives up. Alliance RTW booking sites will let them build it, then fail at ticketing. One plan_route call tells your agent what actually works:
Real response, trimmed for length (the full version includes carrier alternatives and consultant notes for all 7 legs):
That single call just told your agent four things it can't get anywhere else:
- **Alliance RTW fares fail on this trip.** 7 legs prices at 6% bookability - your user would build it, hit a wall at ticketing, and blame you.
- **The build that works:** a per-leg carrier plan - ANA transpacific, Turkish Airlines as the Asia-Europe bridge, each with alternatives and trade-offs.
- **Where to not fly at all:** Bangkok to Singapore is cheaper overland through Malaysia, saving $100-250 and adding a country.
- **What it typically costs:** fare_product_match puts this trip at $2,500-$8,000 economy on an alliance RTW fare, typically $3,000-$12,000 as a custom build.
Those are honest ranges, not quotes - exact pricing on a 7-leg mixed-carrier itinerary depends on fare-class availability the day you book. For a real number, trip_idea_create hands the full routing analysis to an AirTreks consultant who prices and books the actual ticket. Your user gets an expert who starts informed, not a form to fill out.
