I would say it's fairly important to keep in mind the major differences between corporate and airline interviews. Airlines often have quite a few candidates competing for a spot, but usually not quite to the same ratio as corporate. It's really critical to understand that when you interview at a corporate company, you can't ask questions that make it look like you're interviewing them also. You need to show that you already know their situation and want to work there more than anyone else does. If you show that you're just checking it out at the interview, they'll move on to the next person. Best of luck with it!
