How does Southwest do it eol?
Simple. Productivity and a severe lack of "it's not my job" syndrome...
Without question, WN doesn't have nearly the same rigidity when it comes to workrules.
Scheduling of FA's and pilots has pointed out repeatedly, as has the ability to outsource overhaul at-will. Sure, different networks, different requirements, but at the end of the day, they still have more flexibility to schedule their people than AA does.
God forbid a flight attendant on AA be asked to pick up trash on a turn flight that Fleet was assigned to work. First of all, we know the FA wouldn't lower herself to put down her Starbucks or Cosmo to help out, and secondly, even if she did, the FSC who could care less about picking up the trash would probably waste no time filing a grievance over it.
You don't see that type of crap at WN. Supervisor throws a couple bags? The crew takes it in stride. Pilot scanning BP's at the jetbridge? No worries. Flight attendant making boarding announcements? Go for it.
It's a different mentality called "serve the customer and keep the planes moving" which really has nothing to do with their management structure. Whether or not they trust "management" seems to be left out of how they do their jobs and interact with customers.
It's not even unique to Southwest. Lots of airlines manage to form and maintain a collaborative & customer-centric culture, and not surprisingly, their employees don't put up with the sense of entitlement and "that's not my job" attitude that has built up at AA over the past 80 years.
