Yes there is an Indigo and GO.
Go is up and running and ironically (keeping the thread topic in mind) if their website (
www.goair.in) is to be believed they look like aiming for the ultimate in lack of luxury!
They are serviing only water (at no charge) and nothing else "due to circumstances beyond our control".
Not exactly relishing news esp for passengers their BOM CJB flight which takes nearly two hours and leaves at 2010!"But you are most welcome to bring your own food sir" so drawls the chap in their call centre!.
Truly low cost - without a doubt! Reminisicent of the good old train journeys in the olden days when restaurant/buffet cars were unheard of and where food was lovingly prepared by grandma and carefuly packed by grandpa to eat in the train!
