Hello, I have a 13:55 flight from CAI-LXR on EgyptAir in business class (not sure if class of service makes a difference). We planned on touring Giza that morning before heading to the airport. I know the traffic can vary widely. We will not be checking bags. Carry-on only. I am hoping we can check-in online/app ahead of time.

How much time ahead of the flight do we need to ensure we are able to board our flight? More than 1 hour?

Thank you!
