This. The routes that come to mind for me are the 3-4 hour red-eyes like:
SFO/LAX - ORD/IAH/DFW
LAS - ORD/IAH/DFW
SEA - ORD
Also any red-eye that leaves before 10-11pm is tough for me since it's before I usually go to sleep. Even if a flatbed seat is available its tough unless I'm exhausted.
I'd rather spend an extra night than take one of the above (and often have when in LAS for conferences and work is willing to pay the extra hotel night).
