Although I have done lots of mileage runs where a hotel is required, next time look at LAX-DFW(Sat eve redeye)-BOS(Sun morning) and back on Sunday. Viola - no hotel needed, as your Saturday night stay occurred on the plane.

Don't the midcon redeyes leave at 0030 or 0100?
I have a similar issue out of SFO -- the redeyes that help with minimum stays (i.e., the ones that leave before midnight), are the longer ones to the East Coast, which often aren't the maximum mileage routins.
