AirTreks MCP

The primary entry point for any multi-city trip. Give it your cities — it automatically evaluates Star Alliance RTW, oneworld RTW, AND custom mixed-carrier builds, then recommends the best approach. Handles direction detection, backtracking analysis, alliance feasibility, surface sectors, and carrier selection. The customer doesn't need to know if their trip is alliance or custom — this tool figures it out.

Submit the customer's trip to AirTreks — a human travel consultant takes over from there. Automatically runs plan_route to attach the full routing analysis and carrier recommendations to the trip request, so the consultant starts informed, not cold. Use this when the customer is ready to get a real quote. Requires the customer's name, email, at least 2 cities (3-letter IATA codes), a departure date for every leg, and answers to AirTreks' planning questions — call once without questionsAnswers to receive the current questions to ask.

Get a price range for a multi-city or round-the-world trip, drawn from what AirTreks customers have actually paid on those routes. Give it the cities and it returns a per-person range in USD with how much history sits behind it. Use it when someone asks what a trip will cost and you don't have exact dates yet — it needs no dates and no passenger details. It is a range from past bookings, not a live quote, so it will not reflect today's availability or seasonality; it tells you the right ballpark before anyone commits to dates.

Get live, bookable-quality fares for one specific itinerary — actual flights, actual prices, for the dates given. Needs a departure date for every flown leg. Use this once the customer has settled on cities and dates and wants real numbers rather than a ballpark; use route_estimate instead when dates are still open. It prices the itinerary as a single fare, so very long or awkward multi-continent trips may come back unpriceable — those genuinely need to be split across separate tickets, which is what AirTreks consultants do by hand.

Price a complete multi-stop or round-the-world trip and get back several ways of ticketing it — cheapest, fastest, fewest stops — with the actual tickets each one is built from. Use this for trips that will not go on a single fare, which is most itineraries with 3+ stops; use fare_quote when you want one specific itinerary on one ticket. It takes about a minute, so it returns a quoteReference immediately and you fetch the result with itinerary_quote_status. Keep that reference — it is the only way to retrieve the quote.

Break a complex multi-city itinerary into individually-ticketable segments with carrier recommendations. Handles routes that don't fit alliance fare rules — mixed carriers, LCCs, Gulf bridge connections, surface sectors. This is how AirTreks consultants build 90% of itineraries. Use this for any route with 4+ stops, backtracking, or region combinations that alliance fares can't cover.
