Hello

is it possible to find out a delay reason for a past flight ? Egyptair are citing ATC at LHR causing delay to inbound flight CAI to LHR which as a knock on, delayed my flight as it used that aircraft for the return LHR to CAI by about two hours (they are also stating that this flight was late due to finding a slot). The two hour delays caused missed connection CAI to LXR (also with Egyptair on a through ticket LHR-CAI-LXR), resulting in a delay of over 8 hrs as the next available flight wasn't until 06:00 the next day landing at 07:35 - should have landed at 23:00 previous night.

However am not sure if the delay to the inbound from CAI to LHR is relevant to their argument? Any advice welcome and please be kind ! Thank you.
