US Airways Dividend Miles - CRJ flights BWI-PHL

It has been a long time (many years) since I've been on a CRJ. Late this year I will be flying BWI-PHL on one. Will I be able to carry on a bag? I'm heading onward to CDG and would prefer not to check anything all the way through to CDG. Not that it matters for that segment but my international leg is in Envoy.

Thanks
Rich

Yes. They will collect your bag at the aircraft and you will get it back in the jetway at PHL.
