Can I sell a multi city trip through your flight booking API, like London to Dubai then Dubai to Delhi then home?

Yes, multi city trips can be searched and booked through a flight booking API, though how tidily the results come back depends on the airlines and the suppliers behind your search.

Most full service carriers are happy to price several legs as one single itinerary, so your customer gets one booking reference and one ticket covering the whole journey. There is usually a limit on how many legs one search can carry, and some combinations of airlines simply cannot be sold together because the carriers have no agreement with each other. Low cost airlines generally do not work this way at all, so when they appear in a multi city result the itinerary is often put together from separate one way fares rather than sold as a single ticket.

That difference matters more than it first looks. On one single ticket the airline carries the responsibility if a delay on an early leg makes your customer miss a later one, and baggage can often be checked through. On separate tickets each leg stands on its own, so changes and refunds are handled leg by leg, and your customer may need to collect their bags and check in again along the way. It is worth telling them which kind of booking they are buying before they pay, because it changes what happens if something goes wrong.

The practical next step is to run a few test searches on the routes you sell most, see whether the results come back as one ticket or several, and check with us which multi city options your plan and your current supplier mix will support.
