100 segments isn't as bad as it sounds, even living in a hub. I do 75 most years. If hotel prices keep on going up, I'm probably going to start shifting to more day trips for my clients in the 400-600 mile range.
The problem will be that for many OD pairs, United will no longer be cost-competitive for that kind of trip, because the ORD morning bank capacity has been significantly cut. One morning CR7 (or worse yet, one ERJ-145) just doesn't cut it on routes where UA competes with WN, especially when mainline is available at midday or late afternoon.
