Sir I booked flight no AI 821 from new delhi to srinagar dated 12 nov 15.but when i reached the check in counter i was informed that one seat is available in AI 825.so i agreed to board the flight AI825 but didnt get any other proof except boarding pass. I reguested several times for an email regarding the change of flight because its urgently required for official purpose.but no one has responded so far even after several request.and morever the way their staff at t-3 has spoken is pathetic. So i request you to pl take some action regarding the same E ticket no[protected] Dt 12 nov 15
