I'm non-elite and just came back from visiting family in PHL. My gift-filled suitcase was just about 50 pounds (according to my mom's bathroom scale), but I was worried it would register as 51 or something and I'd have to pay a fee. On my sister's advice, I used a skycap instead of going in to the counter, and he never even put it on the scale - just tagged it and sent it inside. Of course, I did give him a nice tip.
