Ok..here goes...

QOL - is not that good if you commute right now. If you live in base you will do long 4 day trips followed by, usually, 3-4 days off. Minimum days off are 12for both reserve and line holders.
PHL base - I think that the new hire classes have been getting split almost evenly between ORF and PHL reserve positions. Just spoke with a new hire on his first day of IOE and he was going to be based at PHL.
Capts. - Most are decent enough but I think that any pilot group will have their share of a-holes that you are going to fly with...this place is no different.
Company's Stability - no such thing in aviation!!!
Interview - my interview was a couple of years ago but very relaxed. Don't remember too much more about it. Maybe someone with more recent
experience could shed some light.
Paint - They are going to have all CL65s painted in the new US Airways paint by the end of Feb. of 2006 (3 a/c have the old paint scheme). UAX ends for the RJs the end of Feb and for the 146s the end of April 2006. 146s are being retired or the lease holders have found new work for them (fire bombers, Asia, etc.)

Let your "dream ship" be the airplane that will pay you the most amount of money for your time. For some people that can be the C172.
That being said...I used to fly the SF340 and liked it a whole lot more than the CL65.
