They're also the "friendly airline", they easily have the most personable and friendly staff. I don't know what they do different, but Southwest employees treat me human and all the rest generally treat me like human trash. It's got to be a company culture thing, maybe connected to Southwest not having a first-class section.
Usually I fly with Southwest whenever possible without thinking twice about it, but this outage and the outage last year are forcing me to reconsider. Better to deal with rude people than to have my flight delayed..
