Hey there,
Well it depends a bit on well you have done and where you are and what position you are in. Airline experience is no better or worse than any other service industry I don't think, although when it comes to your industry it will be hard to predict, because it's not all that big enough to carry statistical weight. I mean if your goal is HBS and you can get a McKinsey job, sure, change industries, why not? Other than top consulting firms, PE firms and VC, there is no preferred industry really, and if you are just great at what you do, then it can be enough for any MBA.
Ultimately also, keep i mind that as wonderful as these schools are, they aren't your ultimate goal, so if you are going to change industries it should be in the direction you want (PLUS help you in terms of the MBA as a bonus), and I'd say that consideration is a lot more important.
Hope this helps out dude,
