mregan,
I flew for PSA for about 2 years, commuting from BOS. Mostly it was OK. To get to DAY it was easiest to go on the Shuttle via DCA then AWAC to DAY. Always the day prior. To CLT was much easier; about 8 flts a day, all 757s and A320s.
However, reserve in CLT is forever. And ever. When I quit I was still on reserve in CLT. Crew scheduling does not tell you what your assignment is untill 1900 the day prior, which is too late to commute down if you have an early show. They also prefer to assign early shows on day 1, and late reserve on your last day. They will not tell you if you are assigned a trip until the last second, even if they know for certain 24 hours prior. Its not a good place.
The planes are good. The crews are good. The lines blow. Management blows. Scheduling blows. The hotels blow. Training is good. There is no growth. There were no upgrades the entire time I was there. FO's are leaving by the gross to go to other RJ operators.
Bottom line, unless you have to live in DAY or CLT, you don't want to work at PSA.
If you want to stay in BOS go to Eagle. Its the best there is here. If you don't have the times for Eagle, try Colgan or Big Sky. Feel free to PM me if you've got more questions.
