The Federation of Indian Airlines (FIA) is an airline industry body in India. Its members are Jet Airways, IndiGo, SpiceJet and GoAir. As of March 2017, the four members of the FIA have a combined 80% share of the domestic aviation market. The functions of the FIA are carried out by an Executive Council composed of the heads of each of the member airlines.
all indian airlines have the word jet in their name.
Goair is an Indian airlane that does not have the word jet in the title so my statement is incorrect. i believe it was difficult because many of the names listed do have the word jet in them.
