The days of scoring an exit row seat for free are coming to an end: Northwest Airlines announced that it will begin charging $15 to book exit row and other desirable seats in the coach cabin of its flights. The consumer part of me considers this to be pure evil, taking away one of the few joys of coach airline travel. But the business part of me understands that this is one of the few aspects of coach travel that airlines CAN charge for; and why shouldn’t they take advantage of that? I’m going to side with the business side of me. This is a great idea (though one that smaller airlines, including Allegiant Air, have implemented recently), and I fully expect other airlines to start their own program like this soon. Bye bye exit rows.
