I am not sure that I should be bothering you with this question but I cannot find an answer nor have I received a response for my request from the airlines.

I currently have dividend miles with US Airways - they talk about purchasing upgrades and E upgrades to a different class of service. Can I purchase an economy ticket and buy 1 upgrade to move up to business or first class? Does anyone know how costly this is? I am just trying to find a reasonable way to get additional leg room.

Thanks for your help. Kathy in PA
