I'm beyond sick of RJs myself. E70s would be ok since they have a decent overhead bin, but the other rj's won't hold my laptop bag in the overhead forcing me to put it under the seat in front of me. I won't gate check my laptop thats just out of the question.
Being MCI based, I have a lot of RJ fligts to hubs. UA only does RJs to IAD from here and DEN seems to be about half RJ and half 757 (go figure), ORD is my only hope for regular mainline service. I fly CO for my TX business and we only have one mainline flight a day to IAH from here, otherwise its all ERJ and CRJ.
