ATPCLiff, vrb115 has a point. If you don't know the answer be quiet. I notice that you post a lot of misinformation.
TSA has at least 22 EMB-145s, only 9 are based out of RIC (even though 12 are used for U). There is talk of getting 5 more for STL this Fall and then more for both STL and RIC for the UA flying out of ORD and IAD. In general the lines are better on the jet in STL, however , with the launch of Pref-Bid it is hard to tell right now. It should take a few months for the Pref-Bid system to work out or not work at all. We'll see. Sorry, no base in NY , IAD, or ORD. STL seems to be the more commutable base but RIC is becoming the more livable base. It's a pretty nice city with a lot to do if you know where to look for it. It's not as big as STL and kind of has a College town feel to it. UVA and UR are a few of the schools there. It's also easy to get down to VA Beach which I think is a lot nicer than the mighty Mississippi. Lately there's been a lot of people buying houses in the RIC area. It all depends on what you like in a city.
7 ATR at STL. I don't know how many are flying. I think several of them are parked.
24 J41s mostly in STL. A handful are in RIC and they are talking about moving more to RIC to hub out of PIT. I don't know how they are going to do the PIT flying.
Again, TSALOUNGE is where you can get the latest on TSA.
P.S. ATPCliff Please stop posting what you don't know as if you do know, which you don't, so don't. Got it!
