so everyone loves to talk about Southwest but I'd say the far more representative example is Virgin America. Despite being the mesia darlings and winning all sorts of awards, it's hemorrhaged money for 6 straight years before posting a meagre profit (http://articles.latimes.com/2014/mar/26/business/la-fi-mo-vi...).

Now that those advantages are disappearing, it seems to be reverting towards the mean (http://www.wsj.com/articles/SB100014240527023039497045794596...).
