At OO on the E175 in LGA.
As far as I know we are still hiring on both airplanes (CRJ and 175). Not sure what the current frequency is with classes but I know a couple months ago we were doing about two E175 classes a month and three or four CRJ classes a month. I waited three months for first available E175 class. Was on reserve a month; flew about 60 hours that month. As a lineholder I fly about 80 hours of month (~90 to 100 credit).
