The Indian aviation sector is facing turbulent times, with airlines like Kingfisher and Air India running up huge losses and struggling to turn around their operations.
Kingfisher's chairman Vijay Mallya says there is a crisis across the whole industry, thanks to rising fuel costs and government taxes.
The Indian government is looking at ways to revive the sector and the solutions are potentially far reaching, as the BBC's Supriya Menon reports.
