I'm going to make a transit in Cairo T2 on two separate tickets and will have tight transit time of about 2.5 hours.
In case that the arriving flight has a delay, I am considering to go through the border and back again instead of using the transit desk, if it's busy there.
I will travel with only carry on baggage. The questions are, if I can use online check in on Saudia flights in Cairo and if it's possible to go through the security and border control with a self printed boarding pass,
