I don't know what Piedmont's official policy is, but what I will say is that there is no reason that even on a flight of this duration, the FA can't do a full beverage service. I worked as a FA for Comair out of CVG and I would always do a full beverage service on short hops like CVG-CLE. Was I running quickly and barely had enough time to collect all the trash before we landed? Sure. But I took personal pride in challenging myself in providing a full beverage service on the CRJ for a 35 minute flight. Bottom line, if the FA wants to do it, they can, just depends how lazy they are.
