Flights API
What is a flight API?
A flight API connects your product to live airfares, lets you confirm them, and completes bookings using another company's airline relationships and ticketing authority. Instead of building airline connections yourself, you call one API and sell flights inside the product you already run.
The supply behind it
What you get access to
Three carrier types in one search, so a traveler comparing a legacy carrier against a low-cost option never leaves your product.
Carrier type
Global network coverage, including connecting itineraries.
Fares and bundles available through airline direct connections.
Carriers whose fares are missing from most traditional air content.
Coverage
500+ across full-service, NDC, and low-cost.
190+.
3B+ fares priced monthly.

Questions, answered
Frequently Asked Questions
What is a flight booking API?
A flight booking API lets your product search live fares, confirm an itinerary and complete a booking through another company's airline connections. The traveler books in your product, and ticketing happens behind it.
Does it include low-cost carriers and NDC content?
Yes. Full-service carriers, NDC content from airline direct connections, and low-cost and regional carriers, priced together in one search.
How do you stop travelers paying for a fare that has moved?
Fares are revalidated before payment. Availability and the current price are confirmed, then a temporary order locks the fare while the traveler completes checkout.
How are payments handled?
Card payment runs through the API with 3D Secure supported, or we can act as merchant of record.
Do we have to take other travel categories too?
No. Flights can run on their own. Hotels, car rental, activities and vacation rentals use the same contract and connection whenever you want them.
Where is the technical documentation?
The CTS Flight Booking API documentation is published and available to your team.
