I am a regular traveler and Jet Airways is always my first choice for domestic travel. One of the best thing about them is their Punctuality. I have traveled with them countless times and not even once the flight got delayed for more than 15 minutes, which is acceptable. Best part, they serve a complimentary meal which is way better than other flights overpriced food menus. The only minus point I found is leg room between the seats, which can be a problem for tall people. Overall I recommend you all, use Jetairways for your travel.
Cheers!
