Decoded: What is the difference between low-cost and full-service airlines?

As the Tata Group looks to merge its full-service carriers, Air India and Vistara and low-cost carriers, Air India Express and Air Asia, the airline will have a more integrated operations structure allowing it to operate more efficiently.

Talking about the rearrangement of operations, an Air India official said we have two concurrent integrations. One between two low-cost airlines, Air India Express and AirAsia India, and the other between the two full-service airlines, Air India and Vistara. The official said the group will integrate to make one full-service and one low-cost airline group.
