Dear sir,
On 30.08.2017, air india flight ai635 from indore (Idr) to delhi (Del) got delayed by couple of hours. The flight was supposed to reach delhi by 11:35am instead it reached at 13:30am which caused me to missed my flight from delhi to london, flight no 9w 122 at 13:15 hrs on 30.08.2017. I had to re-book another flight and paid rs 47, 595. This is my personal financial loss. I need a compensation of the same else i've have to take this case to consumer court.
