What we may see is CARMEN building AM and PM rotations (commutable on one end but not the other) which could help mitigate fatigue issues associated with the late night arrival followed by the early AM departure 30 hours later...or the red eye followed by a hotel layover followed by another leg later that day.

In the spirit of "mitigation," simply negotiate "pull-down" language in case the ADG/DG provisions get too onerous on the pilot group.
