Format of sending a complaint letter to an airline company and asking them to cancel flight that you have booked previously and now due to some emergency you will not be able to make that flight.
Complaint Letter to Airline for Cancelled Flight
To: Directors of Air Asia
I am writing this letter in regards to a last-minute cancelled flight by Air Asia. I was departing on a business trip with multiple connecting flights and after the cancellation by Air Asia in Malaysia, I found myself stranded in Kuala Lumpur Airport.
This is extremely unacceptable as I was on a business trip and it is unprofessional to arrive late. While I understand that cancellations are sometimes inevitable, a passenger should be informed about the cancellation well before the time so that he/she may make other reservations. Because I did not receive any prior notice, I was stuck in the airport for almost an entire day.
I hope that you will reconsider your policies and, in case of any cancelled flights, you should inform the passenger well before the time so that they may make other arrangements.
