Travel demands have made me a frequent traveler of many years (My advantage member number in american airlines is 3k77cd0).
It is the first time i travel air india, and i found your service to be fair.
But on the flight mentioned you failed to return me home on time.
Here is what happened on march 7:
Me and my wife were notified that the flight ai 139 departure time was changed to 15:30 and we had to rush into the airport from another connecting flight.
At the airport the message was that the flight was instead delayed from 15:30 to 18:10.
Then, already at the gate an announcement came that it was postponed to 19:00 and after a while to 19:30. The flight took off finally at roughly 20:30.
One could have thought that the company would make an effort to make the actual flight time shorter, but instead of
Landing in israel at 7:45 pm on march 7 as originally planned, we ended up landing at 00:18, the next day, so an accumulated delay of about four and a half hours – namely a half working day!.
As a result of this delay we were stressed, uncomfortable, lost the last train home and had to take a special taxi at night ($100 cost), hardly got to sleep and had to shorten my working day on march 8.
I therefore ask for your full compensation for this trip.
I have every confidence that you will compensate me properly for this unexpected and unpleasant delay, considering the high standard of service and
Consideration your company promises to its customers.
Sincerely,
Prof. Uri peskin
