a) Dont pick a seat online, most times the seat map shows a lot of occupied seats which are really free. Call for seating
b) On EY's own aircraft, the seats are staggered so every other row has an A seat, rows 5,7,9,11 and all the A and K seats are good.
c) But some flights like EK103 to New York don't use EY aircraft at the moment, they have leased Air India planes with inferior seating
