What Desdi said. No one has an idea what "red eye plus 1" is. But no same day starts are allowed unless you choose to.

Speaking of redeyes, what are Spirit's redeye rules?

JB:
25.A.7 (planning):
Duty period with a flight segment that touches the redeye period shall not exceed 10 hours
Duty period with a segment departing between 0000-0500 base time shall have 16 hours rest prior and 14 hours rest following
12.B:
Duty period in which a pilot operates touching the redeye period (0100-0500) shall not exceed 12 hours
Pilot may not operate flight after completing a segment that transits more than two hours of the redeye period
Base report before 1700 precludes pilot from operating a flight that departs in the redeye period
11 hours min rest before/after duty period scheduled/actual in the redeye period

Honestly it would be nice to just have a full copy of the SPA contract to thumb through. Is it available on the ALPA site?
