After having done 6 segments with MS, I conclude that the MS-seat-layouts are one of the rather misterious things in Egypt
I always booked the right-hand window seat in the 2nd row:
-On the 737-800, biz starts with row 8. Although I had reserved "window seat 9D", I got window-seat 9F at check-in.
-On several, but not all, small Airbusses, biz starts with row 1. Although I had reserved "window seat 9F", I got window-seat 2F at check-in.
-On the E170, biz starts with row 20, and the curtain is movable.
