I was reading the brochure about the US Airways Club on a recent trip. I got switched from Northwest to US Airways

(I always fly Northwest) and since I am a member at the Northwest Club and all the drinks are free, I saw in the brochure that US Airways Club charges for certain drinks. Is this true? The fee for the US Airways Club is already higher than the Northwest Club. Is there something that US Airways Club offers that justifies the larger cost and the charge for drinks?
