Somehow, I don't see SWA adopting a lot of ATN procedures. Not that they're not open to change, but you don't turn an aircraft carrier on a dime either.

Frankly, why mess with success? SWA has had its issues, but they remind me of an Alaska Bush Pilot legend Harold Gilliam: "He thrill 'em, chill 'em but no kill 'em Gilliam."
