I don't know if I buy the no fleet growth thing co-wide. That's based on the ExpressJet WSCODs AND the new widebody luxury liners being balanced by transfers to Piedmont. Seems unlikely bro.
The CRJ is a black hole though, as others have said. My CRJ reserve bros do seem to fly slightly more than us 145 FO's, but we're talking averaging 15/hrs a month instead of 5-10, and unlike the 145 there's no hope of ever escaping to a glorious line of 5 back-to-back 1hr15min turns in NYC.
