I don't think any of the former US airways lounge locations EVER have had showers. That was an AA-only thing for clubs that have international service somewhere over the ocean. Nothing for Charlotte, Phoenix, DCA, where else am I missing that uses an old US location? Boston no, too. Edited: Another poster said Boston does have showers. I'm uncertain if that's a former US location or an original AA location

Hopefully the new Charlotte club will when it opens... whatever year that will be. New LGA has showers (brand new DCA E does not, neither will new Denver club... We will see about new Austin once it opens in a few years)

Yes for Chicago Dallas LA Miami Raleigh , but I don't know where else.
