Jet Airways plans to do away with first-class seats in its Boeing 777 planes that are operated for long-haul flights as it works on cost-cutting measures, a senior airline official said.

The carrier, earlier this week, told investors about its plans for strategic growth where the key focus would be on cost minimisation. Currently, the full-service carrier -- in which Gulf carrier Etihad has a 24 per cent stake -- has 10 B777 aircraft. These planes have eight first, 30 business and 308 economy class seats.

In a presentation to investors on November 20, the airline said it would increase the number of seats in B777 planes, to around 400 seats from 2019 onwards, from 346 seats.
