I think VS did have nightstops on the west coast for some time but realised that crew were both fatigue and hitting their 900 hours faster than they could have imagined. We have a couple of 3 day trips to LAX and SFO and 4 day trips to CPT where we position one way and work the other. Even those ones are tiring.
Full-time crew are very close their 900 hours. Part-time crew and particular those on 75% are way above their limits. Logically they should average 675 block hours a year but many are 100 hours plus on top of that.
No, you probably hit the nail on the head there. WW crew are unflexible at disruptions whilst EF are. I don't even know what your disruption agreement looks like (or even if you've got one). All I know is that you can claim to have 18 hours rest after you have gone out of hours (?).
