The last 2 trips I have done to India, I have flown J, ( I am only in India for 2 days)
It was well worth it (got great deals because of a sale started by Qatar)
The thought especially of not having to worry about getting to sleep on the return from Bom (1.55am) was worth it alone. and the fact that since I dont check bags, knowing that the overhead bin would be empty made it even better.
Granted I dont do this everytime I am going, but it sure feels great when I do
