Well, as a primarily business traveller, I can certainly live with their product. I don't care about meals, in-flight-entertainment, fancy shopping mall terminals or the sense of flying on a so-called "prestige" airline. On short-haul trips I just want to get to my meeting on time with the minimum of fuss and get back home again - on time.
Also, since I work in a highly competitive business, the cost of travel is vitally important to maintain profit margins on a business opportunity while remaining competitive on price. I have no reason to fly on anyone other than the cheapest, provided they're safe and reasonably reliable.
