I've noticed in the three airline forums I frequent most, NW/CO/DL, one of the bigger gripes is the slow creep in regional jet service. I actually managed to never fly one until about two years ago, but now seem to end up on them a few times a year. I still try to avoid them at all costs, but has any one managed to avoid them 100% on domestic mainline flying (WN & Jetblue of course don't count! ).
