About IndiGo
IndiGo is a low-cost airline and a very familiar name to anyone who flies within India. It is headquartered in Gurugram, next to Delhi, and its main base is Delhi's Indira Gandhi International Airport (DEL), supported by large operations in Mumbai, Bengaluru, Hyderabad, Chennai and Kolkata. The domestic network reaches deep into smaller Indian cities. International flights go to the Gulf, South and Southeast Asia, Central Asia and, more recently, a handful of longer routes. Most aircraft have a single economy cabin, although a business-style product is sold on selected routes. IndiGo is not an alliance member but has codeshare partners.
IndiGo is an obvious airline to check for travel within India. On IATA.co you search live fares in the booking portal or through the flights API, and you pay from a prepaid balance. IndiGo fares appear in your search results whenever our flight suppliers offer them for your route and dates. Fare families differ in what they include, so review the details before confirming.
IndiGo airline codes explained
IndiGo uses the two-letter IATA airline code 6E and the three-letter ICAO code IGO. The IATA code 6E is the one shown on tickets, fare displays and booking screens, while the ICAO code IGO is used in air traffic control and flight planning.
IndiGo is a low-cost carrier, based in India, operating mainly from Delhi (DEL). It is not part of a global airline alliance.
Booking IndiGo fares as a travel agent
Travel agents book IndiGo fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live 6E fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. IndiGo results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search IndiGo (6E) through the flights API
Developers and agencies can run the same IndiGo search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code 6E and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
