While I'm not a UA flyer, I've basically given up on MHT. I'm on CO out of there on Saturday (doing MHT-EWR-GSO) but I've been flying to BOS a lot more lately due to the fact that BOS has mainline on every airline, while UA, NW and US (who I refuse to fly) are the only ones with mainline at MHT (and connecting from GSO to MHT via ORD/DTW is a bit out of the way; when I do DTW, I often get 2-3 hour layovers there).

Shame too since MHT is a real easy airport to use, but given the choice between RJs and mainline, the big jet is going to win every time.
