Living in PHL, your QOL will be excellent at AWAC...and there is lots of open time available in PHL. As a RSV picking up opentime is at the discretion of crew scheduling (even moreso than lineholders) but you might be able to make some extra $$$ easily if interested.
RAH is a great, growing company with fast upgrades and a decent contract, but I think you'd be better served (if you have a choice) going with AWAC for PHL than CHQ and being forced into commuting to BUF/SDF/IND/STL/CMH, or God forbid, CRP for the CRJ.
