Thank you that’s helpful info. I wasn’t sure if info about the previous inbound flight was relevant or not. Will see what Egyptair can provide I think and take it from there as think it’s up to them to prove what happened not me. We were told nothing at Heathrow other than it was delayed coming in - but I do know it was in fact late setting off from Cairo so not sure if that’s because they’d been told by Heathrow to delay departure from CAI. The Egyptair reply said it was LHR ATC no mention of ATC Cairo. Thank you again.
