Republic has been operating out of the C and B terminals most recently, and early on did operate out of the F terminal during the transfer of aircraft from Mid Atlantic (please reserve opinions on this matter...). A base in PHL is allegedly here, just waiting on the formal vacancy announcement- and a new shipment of KY with sand. Republic will continue to operate from B/C for the forseeable future. The only thing that may impact that is the delivery of more 190's for USair. In general, the 170 took up just a bit too much room on the F gates, and it became difficult to park one 170 per gate without having to skip a gate in between.
RW maintanance is on the C terminal, and the crew room will be there too, so we shouldn't be stepping on AWAC's toes.
