You are correct. There are some areas that are "better than" FAR. Not many, but some.Read the contract. As bad as it is, CALAlpa still has domestic duty time limits that are less than the FAR's (depending on the show time).
I don't know if there is a copy of the "redbook" contract that was in effect at CAL before the '83 strike but it's quite likely that it contained domestic duty time limits more restrictive than the FAR's.
I would be shocked if there is a passenger airline contract in force that is better than what existed at that same airline before deregulation.
