Not sure what the allure about going to SW nowadays is. Yes, yes. I get it, they make descent money. But I'm not sure that does it for me. Came to Spirit 7 years ago, been left seat for almost 2 (flying with my favorite captain!), got my guaranteed 4 days off in a row per the CBA, work some OT and credit an average of 110 hours a month (not bad money at all). Currently half way up the list in base, and almost top third of the master list. Descent layovers (just spent 24 hours in a Cabo resort), excellent crews (and some very young, fun, hottie F/A's). Aggressive growth, new jets, profitable business model (read ATW's "The New Southwest?" article). You don't need a Space Shuttle type-rating, or be an alumnus of the Fighter Weapons School to be eligible, although it might be a plus. Many ex-World, Omni, DHL and most recently expats from Etihad and Emirates are being hired. 24 a month.
Maybe the SW thing is a little overrated. But might be worth a shot.
