Are you kidding? You must not have had status with any other airline. Trust me, other airlines treat their frequent fliers much better than SW treats theirs. Expedited security, special customer service numbers, the ability to choose (weeks in advance) the best seats on the plane, early boarding (without the ridiculous need to race to the computer and check-in 24 hrs ahead of time), free alcoholic beverages, frequent flier status bestowed on anyone traveling with me on the same reservation, free access to airport lounges... I get all this and more in exchange for my loyalty (and 60 or so flights per year). I would never consider SW anymore.
I did fly SW (and was relatively happy with them) when I was 22 and wanted a sub-$170 round trip ticket to Vegas or something. I only flew now and then and had no issues with being treated like livestock. THAT is the kind of customer SW has catered to for forever. Heck, when they started, they were designed to compete against regional bus transportation (think Greyhound). I'm not making this up. You can find it in any SW case study.
They've just started trying to appeal to business fliers and they're adding loyalty programs to attract them. IMO, they are a very long way from really competing in that space at all.
SW is a well-run business and I'm sure if they commit to being successful with frequent business travelers they will be.
