RSV at RAH is painful. I have >5.5 years between FO and CA straight. I DO NOT recommend RSV here. This CBA and the last CBA as well as crew scheduling training are predicated on the idea that "no one spends more than a month or two on RSV". Pm with questions but I doubt it's much better anywhere else really.

I "believe" but don't know that RSV at RAH is a little worse because you'll sit out of base RSV any time they don't use you in base, you'll rarely break guarantee, and you will DhD about 25-35 hrs a month. Also Long call is based on system-wide reserves, it is not linked to a base, there is no guarantee of long call at all. In fact, they can award it to no one in your base. I've bid for it for several months but never been awarded. I got a line or RSV. Your mileage may vary.
Good luck.
