I say interview. Options are always great. The bad thing is that you will never know you made the right decision until the end. The thing to remember about airlines is there are those that have been bankrupt and those that will. At one time or another every airline has been the darling of the industry and been the butt of it as well. SWA has not been through any really tough times yet and by no means do I wish any on them. Just remember that NO airline is immune to problems. Good luck.
