    What Is a Flight Booking API for Online Travel Agencies?

    A flight booking API for online travel agencies is a connection that brings live airline fares, seat availability and ticketing into an OTA's own website or mobile app. Travellers search, compare and book flights on your platform, and their e-tickets are issued automatically under your brand.

    It's the simplest way for an OTA to sell flights to travellers directly. You plug in one flight API for your OTA instead of building separate connections with every airline, GDS and low-cost carrier.


    API FEATURES

    Everything Your OTA Needs to Sell Flights in One API

    Our real-time flight booking API for OTAs gives your website and app what they need to search, sell and manage flights, from a traveller's first search to their final refund.


    1. 1Show more fares in one search. Travellers see live airline inventory from GDS, NDC, low-cost carriers, SOTO, private and series fares. It all comes through one flight aggregator API, with no separate supplier connections to manage.
    2. 2Confirm bookings the moment travellers pay. The PNR and e-ticket are issued automatically, so there's no hold queue and no manual ticketing.
    3. 3Give travellers the full picture before they book. Fare rules, baggage allowance, seat maps, meals and special requests come back with every search, so fewer surprises reach your support team.
    4. 4Let travellers manage trips themselves. Cancellations, date changes, reissues and refunds all run through the same API, which means your website and app can offer self-service after booking.

    FAQs

    Frequently Asked Questions About Our Flight Booking API for OTAs

    A B2C flight booking API connects live airline fares, booking and ticketing to a website or app that sells flights directly to travellers. Travellers search, book and receive e-tickets on your platform, while the API handles airline connections, pricing and ticket issuance in the background.


    Start by choosing a flight API provider and testing in its sandbox. Your developers then connect flight search, booking, payment confirmation and e-ticketing to your website, run full test bookings, and go live after certification.

    The steps are the same as for a website. Your developers connect search, booking and ticketing to your Android and iOS apps through the same API. Because one API powers both apps and your website, fares, pricing and bookings stay matched across every platform.

Look for GDS, NDC and low-cost carrier fares in one response, instant ticketing, self-service changes and refunds, and a sandbox to test in. Travel Terminus offers all of these, with 99.9% uptime.
