We've booked Business Class seats on a flight from Cairo to Aswan aboard a 737-800. When I pull up the seat map to select seats, it shows rows 8 thru 14 (no row 13). It show 2 by 2 seating but I can't figure out why the rows don't start at row 1. The seating map on the EgyptAir website has no row numbers, and the number of seats doesn't line up. The map also doesn't match the map on Seat Maestro. Can anyone explain this?
