If the aircraft is their 777s, one word of advise : DON'T.

Their 777s have literally 38in pitch which makes them very uncomfortable. I've only flown on their F and that was even a torture on a 12 hour plus flight as the most uncomfortable seat in F/J anywhere....

Save your $ and spend it on a nicer hotel to rest your weary head after the journey.

FYI - You do know that Egyptair is a DRY airline, right?
