I was travelling on BA 297 from LHR to ORD on Jan 17, 2023. The flight was scheduled to depart at 3:30 pm local time and departed at 8:30 pm. I would like to file a compensation request and was hoping someone could provide me with the 'official' IATA delay reason. For what it's worth, the aircraft was damaged on the ground so passengers were asked to deboard since the aircraft was uncomfortably cold and it was going to take a couple of hours to find the replacement part and repair personnel. In the meantime, the pilots timed out and new pilots were called in but the cabin crew stayed on for the flight despite the delay. Crew was phenomenal and did their best given the situation.

Thanks!
