Hmmm.... thanks for the feedback but it is a bit frustrating that it is hard to get a definitive answer about the type of C class.

If the seating is Euro style and being DRY then no uway is it worth a cent more.
I am going to try to call Egyptair in NYC, but I suspect that I will get some misinformation.
It certainly looks like US style F class but.......

If you look further, the premium cabin on the A300-600 looks odd.... 2-3-2 in some parts and 2-2-2.
Also, the 321 seatmap looks like Euro style but notice that they label the premium seats as Horus/ Business whereas the 735 is designated First class.
