There are many needed QOL improvements that need to happen that don’t require the Magna Carta & aren’t open to interpretation.

Schedules can’t be built with single days off
Ground deadhead only LL, period
RAP’s can’t be moved unless forced by legality
Vacation pay trips missed & you can slide 3 days
Min days off increased
Min pay 5 hours
Red eyes one leg go to hotel
etc…..
I’m sure you all can think of dozens more.
