Address:

744101

We booked a flight from delhi to port blair for 7th june 2018. The time for take off from delhi given on the ticket was 11:50. When we were about to reach airport, we received a call that the flight at around 9:20 am that the flight will take off. Subsequently i came to know that the timing was changed.in this situation, it was not earlier intimated by airlines and hence would request for a rescheduling of ticket. It was the ticket for 5 persons. We being from island cannot afford to stay in delhi for few more days and purchase new ticket.

Please take it on priority and kindly help us avail rescheduled tickets.
Pnr of ticket is cc95yq.
