You guys forget: that when SWA started becoming a player (mid 1990's), most airlines either required a type rating and/or training bond (indentured servitude?) when you started so it was not unusual then. They are in the position now where they can ask for it.

Also, the reason Delta went under was, even with their higher wages, their Quality of Service / Travel Experience sucked compared to SWA. And evidently it's not all price, because SWA has been raising fares all year long, with no drop in business.....
