The flight from mumbai to ahmedabad on 21dec has been cancelled and rebooking done and the ew timings are other convenient to us. Repeated requests made it airline has reuse to help and consider.
Booking is done through ibibo and they also are ready to help us but airline is saying as delay is 1 hour 50 min and not 2 hour (Just short of 10 min) they will not help in this matter.
There is an important function to attend and connecting booking by train is getting disrupted, so asking or this favour.
