What is the airline code for IndiGo Airlines?
The IATA airline code for IndiGo Airlines is 6E, and its ICAO code is IGO. The two-character IATA code prefixes the carrier's flight numbers, for example 6E123.
IATA airline codes are two characters and can reuse letters over time, so a retired airline's code may later be assigned to another carrier. ICAO codes are three letters and are more stable, which is why flight plans use them.
Where the 6E code comes from
6E is IndiGo's alphanumeric code, chosen at its 2006 launch and turned into a brand in its own right: the airline markets seat products and services under 6E labels, and the pairing is often read aloud as "sixie". It is the clearest example of an airline embracing an arbitrary code instead of hiding it.
IndiGo is India's largest airline by a wide margin, carrying well over half of the country's domestic traffic as of the mid-2020s.
