Airline APIs in India: IndiGo, Air India & How to Access Them

If you're building a travel product, you'll want to connect to airline inventory — often starting with a search like "IndiGo API" or "Air India API." Here's how airline API access actually works in India, and the practical way to reach every carrier at once.

Do Indian airlines offer public APIs?

Mostly, no — not open, self-serve APIs for individuals. Airlines distribute their fares and inventory through GDSs, NDC connections, and authorised aggregators/consolidators rather than handing out public API keys. Direct airline API access typically requires a commercial agreement, volume, and technical certification with each carrier — impractical for a new agency.

The major Indian carriers

• IndiGo (6E) — India's largest airline; distributed via GDS/NDC and aggregators.
• Air India (AI) and Air India Express (IX) — full-service and low-cost arms, available through the same distribution channels.
• SpiceJet (SG), Akasa Air (QP), and others — reachable through aggregator platforms.

Chasing each airline's API separately means multiple agreements, multiple integrations, and multiple things to maintain.

The practical route: one aggregator API

Instead of integrating each carrier, use a single flight booking API that already connects to all of them. You get one integration, one set of endpoints, and coverage across every major Indian airline plus international carriers — with search, pricing and ticketing handled for you.
