Flight back from Luxor in Egypt. The hotel missed our 6am wake-up call, so we had to rush to the airport without showering, only to find that some government minister had taken our London-bound EgyptAir plane and diverted it up to Cairo to fly some family members to Moscow. We then had a 13 hour wait at the airport, which was being refurbished, while EgyptAir staff outright lied repeatedly to everyone telling us all that the flight would be "in two hours". Thanks to the building works there were no shops, no restaurants, no cashpoints with money in them in order to buy anything from the small food kiosk, not even water. Plus someone had stolen all the toilet paper out of the toilets and was happily selling it sheet by sheet back to travellers in full view of security, and due to the refurbishment the aircon was on the blink.
A plane finally arrived and we boarded, only to find that it was a smoking flight and we were one row in front of the smoking section. Which meant that the entire flight to London we had people from further up the plane coming back and standing right next to our seats to light up. Like travelling long-distance in a car with smokers and the windows up. The food served was dried, overcooked and shrivelled due to the wait, the staff couldn't have given less of a toss about anyone, and the temperature inside the plane was uncomfortably hot. Arrived back in London 14 hours late, stinking to high heaven of tobacco fumes and sweat, and still had to make it back home from Heathrow.
Never fly EgyptAir. Ever.
