How travel agents book IndiGo
GDS distribution
IndiGo signed its first GDS agreement with Travelport in September 2016, connecting by API, and in September 2024 agreed to distribute NDC content through the Amadeus Travel Platform. IndiGo's NDC FAQ says GDS access is open to IATA-accredited agents.
NDC
IndiGo offers its 6E NDC content on the IATA NDC 21.3 schema through direct NDC APIs, GDSs and authorised non-GDS aggregators. Direct access is open to IATA and TIDS agents through the 6E developer portal. Amadeus reported in September 2024 that NDC booking and servicing were already live in the UAE and Singapore.
Direct channels
Direct bookings on goindigo.in and the IndiGo app. Developers and agencies register on the 6E NDC developer portal (developer.goindigo.in) for API keys.
Notes for travel agents
Non-IATA agents are told to request IndiGo NDC access through their GDS provider, and technology providers must be 6E authorised partners to resell the content.
On ReservationHub
ReservationHub gives agencies GDS content from Amadeus, Sabre and Travelport plus NDC and low-cost channels in one platform. See the full list on our integrations page.
History of IndiGo
IndiGo started operations in 2006 with a single aircraft and grew on a simple formula of low fares, on-time flights and one main aircraft family, the Airbus A320. By 2016 it was flying 112 aircraft, and in November 2015 its parent company, InterGlobe Aviation, listed its shares on India's stock exchanges.
The airline added ATR 72-600 turboprops for regional routes and moved its jet fleet to the A320neo and A321neo. It also began working with the global distribution systems: in 2016 it signed its first GDS deal with Travelport, using an API connection rather than traditional fare filing, and in 2024 it agreed to give agents its NDC content through Amadeus.
From 2025 IndiGo began moving into long-haul flying. It used damp-leased Boeing 787-9s, took its first Airbus A321XLRs, and in October 2025 confirmed an order that raised its firm A350-900 commitment to 60 aircraft. It deploys the A321XLR on routes such as Delhi to Istanbul and has a codeshare with Turkish Airlines.

IndiGo: frequently asked questions
What are IndiGo's airline codes?
IndiGo uses the IATA code 6E and the ICAO code IGO, with the radio callsign IFLY. Its three-digit ticket prefix in the IATA register is 312, so IndiGo tickets start with 312. Flights are shown as 6E followed by the flight number, for example 6E 0011.
Does IndiGo offer NDC to travel agents?
Yes. IndiGo publishes NDC content on the IATA 21.3 schema through its own APIs, through GDSs including Amadeus, and through authorised aggregators. IATA and TIDS agents can connect directly through the 6E developer portal, while non-IATA agents are told to go through their GDS provider.
Is IndiGo in an airline alliance?
No. IndiGo is not a member of Star Alliance, oneworld or SkyTeam. It works with partners individually instead, for example through its codeshare with Turkish Airlines, which connects IndiGo passengers to more than 50 further international destinations through Istanbul.
What aircraft does IndiGo fly?
Most of IndiGo's fleet is Airbus A320neo and A321neo aircraft, with ATR 72-600 turboprops on regional routes. It has added Airbus A321XLRs for longer routes, operates damp-leased Boeing 787-9s, and has 60 Airbus A350-900s on firm order.
