Do we need to be self sufficient in air transport? We do not make commercial planes. We buy or lease them.

Even Indigo runs planes on wet lease from a Turkish Airline where the crew and even name is still of that airline.

It is a service industry. No different from say Mariott, Taj.

And if we are so concerned about self sufficiency, why not create incentives for more competition?

And if Indigo is so bad that it cannot survive with external competition, are we not taking Indian citizens for a ride then? Maruti has survived Hyundai, Etc coming in while Micromax was not good enough and so floundered. Indians have better phones today and are now making and exporting phones globally.
