Mesa...We are nearing the end of our current slate of EJET deliveries (end of July), but there's still time to get on board and not be stuck on reserve for too long if you don't delay. We are VERY short on FOs right now. I keep hearing persistent rumors of additional EJETs coming, but nothing official yet. If they do come, then you will probably see the left seat reasonably quickly provided we can still fill classes.
If you want to fly a lot, then our flying out of IAH will fill that need. I see several 90+ hour lines being awarded to those who want them. Most of our legs are long (BDL, YUL, YYZ among the longest) so the trips are pretty productive without being too tiring.
