Recently I did travelled from indigo for my travel from Mumbai to Muscat.
Check in : Boarding and check in are smooth.It is done easily.
Airplane Seats : Seats are very uncomfortable and are thin base finding it hard to seat for 2 hours The space between seats are less which make it difficult to stretch your leg.
Cabin Crew : Initially they greet you with warm welcome but during flight seeems to be hard especially when you ask them for water.
