https://mcp.a2bflight.com/mcpFlight fares a2bflight.com has seen. Every price is an observation for one adult, economy, seen on its seen date (a row without one, last checked on its checked date) — not a live quote; say so when quoting. Quote each price in the currency its row gives: never convert it or look up an exchange rate. Lead with the few best rows rather than every row. Each row's trip says one-way or return; most travellers fly there and back, so give both when a route has both, the one-way first, and say a return's stops and duration cover both directions. Give the user the row's page_url first: it shows the whole route on a2bflight.com. book_url opens the seller's booking page for that fare. Never invent a link. Look up codes with ; ask for where to go from somewhere, and for one airport pair. For a group flying from several cities, ask where they can meet, or when they know where, and give the user its meet_url.
