Following suit with Northwest's 2006 concept, US Airways is making the move to charge customers for the best economy class seats. Most travelers consider themselves reasonably lucky to get a window or aisle seat assignment, and the airline is taking luck out of the equation. The extra charge will only apply to the non-middle seats in several front rows of the plane — there's no extra leg room, but you'll be out of the plane faster than passengers who didn't pay more.
As of May 7, US Airways "Choice Seat" program will ask you to pay $5 when you reserve an aisle or window seat in the front rows of coach. This initiative follows their February announcement that checking a second bag will cost an additional $25. Five dollars might be worth the added value of sitting in the front of the plane, especially if you have a crunched-for-time connection or have serious issues with sitting in the middle.
