Indigo flies as a budget airline(serving complimentary water) between Muscat and Mumbai but the ticket rates are exorbitantly higher than other full service airlines like Jet Airways, Oman Air and Air India.
I fly every month due to rotational job and am surprised what makes Indigo keep its prices so high.
A year back their rates were competitive and I used to fly with it, but due to insensible ticket costs I am flying Jet and Air India. To give an example, December return ticket of Jet is 21000 while Indigo is asking 31000.
