Thanks for posting the detailed info, Carajillo2Sugar.
Sorry to divert this thread but I noticed that passengers taking a KLM flight ex-Cairo this morning were only allowed to take hand luggage.
Only 155 passengers out of the 247 booked actually boarded the flight as they didn’t want to travel without their checked luggage.
KLM is a 6th freedom carrier, I imagine these would be passengers who would be travelling long-haul beyond Amsterdam.
As far as is known, no other European carrier has so far enforced this rule for flights departing Cairo.
