My wife had booked an online ticket from Canada with an International Credit Card for her father to travel from Jaipur to Mumbai and we were in Mumbai a day before the actual flight assuming everything had been done a month in advance without any problems.
Thats when everything went wrong. We called Indigo in the afternoon to get the ticket extended and thats when they told us a lot of different things .. none too clear. First they said we should fax them a copy of my wifes credit card as its an international one to prove that its booked by her for her father. We said no; then they said her father should carry a copy of the card for the flight. We actually went to a PCO/Xerox center and ensured that her father who is old and suffers from health problems could be at a PCO in Jaipur where we could fax it.
Next day; he goes to take the flight with the papers. They check in his luggage; do the whole process and afterwards call him back from the waiting area and tell him they cant accept his ticket. He explains everything and they force him to buy a new ticket for twice the price we paid for the original ticket.
Eventually we had paid for 2 tickets for only 1 passenger. We spoke initially with their call center agents then with their floor manager; then with the airport manager; etc .. Each time we were told .. give us 24 hours; give us 48 hrs; give us 72 hrs. It actually took us around a month after the flight and only 35 to 40 phone calls and 2 visits to the mumbai airport counter to get our money back.
I dont think anyone should be treated the way we were. Fly any other airlines but please dont fly Indigo
