Can my customers see how long each flight connection is before they book?

Yes, customers can usually see the time between flight segments before they choose an itinerary. A flight booking API normally provides the arrival and departure times for each part of the journey, allowing the booking portal to show the connection time in plain language.

The details available depend on the airline, supplier and API response. The portal may also show the connection airport and terminal when that information is supplied. Terminal details can be missing or changed later, so customers should not rely on them as final travel instructions.

A longer connection does not always mean an easier journey. Some itineraries may require the traveller to collect baggage, change terminals or airports, pass through immigration, or check in again. This is especially important when separate tickets or a self transfer are involved. The API can only display these warnings when the necessary information is available from the supplier.

Before offering connecting flights, check which connection details and warnings your flight supplier sends, and make sure customers review the complete itinerary and current airline guidance before booking.
