United and Delta will be parking 300 or so large RJs by end of 2015! EXJ operates the vast majority of them, United has outsourced over half the large RJ they can put on the line before they have to add a NB fleet and Delta only has 30 more large RJs to be awarded. Not flaming as I work at a carrier with mainly 50 seaters but the future of EXJ isn't looking as bright as some might led you to believe. Attrition is high so that's a good thing.
