Of the 3 choices you gave, I'd probably choose to fly IndiGo.

Kingfisher is bankrupt. Lots of cancellations, unreliable service, poorly maintained cabins, demoralized staff who haven't been paid in months. Definitely avoid

Jet Airways is alright assuming you can deal with the fact that you are flying in an advertisement. I find it extremely annoying and tacky. I'm sure some other forum members who fly 9W more regularly can fill you in on exactly why you should avoid it.

IndiGo is a no-frills low cost carrier. Reasonably reliable, clean planes, professional crews.

And FWIW, I would definitely suggest Air India (Indian Airlines) on this route. The flight has a good on-time record, the food is unparalleled in the sky for a hop of this length, and the product is comfortable.
