Reserved seats?: Lately, some bargain airlines started selling "reserved seats" on the plane. However, the seats are all quite similar and even if you don't reserve a seat when you book your ticket you will still be able to choose your seat when you board the plane or you will be assigned one at the check in desk. So you can easily avoid paying extra money in order to reserve your seat.
