Additional fees seem to be the way of air travel these days. The majority of major airlines have begun charging for a second checked bag, and other carriers offer a veritable a la carte menu of services including meals and curbside check-in. We’re also seeing additional costs for leg-room, with some airlines even considering charging extra for aisle and window seats.

Midwest Airlines is the latest carrier to put a price on leg-room with their Signature Seating. They’re not sticking you in a middle seat if you’re not willing to pay, but they now offer a seating choice on their MD-80 aircrafts. You can purchase a standard airline ticket for Saver Seating, or you can kick in an extra $65 for Signature Seating, which will be “arranged 2-by-2 with exceptional legroom.”

There will be 12 signature seats on select Midwest Airlines flights. Keep reading to see the routes that will be affected, and decide if extra comfort is worth an extra $65…
