Spicejet
It is a really good airline
It has planes in and out of almost every major city in India
I fly very frequently with spicejet.
They have very clean seats and aircraft.
They usually have better leg room than the other airlines.
And almost like the 15 times I have flown there has been No delay
They are very punctual.
The flight attendants are very helpful too
Overall it is a really great and one of the best running in India right now.
