But SWA has a loyal following and this plan caters to some. People have a choice and can and will fly on another airline based on price, convenience and value.
I think that's the danger. People equate SWA with a cheap ticket and not getting screwed by extra charges. That's what creates loyalty. Unfortunately, that makes you vulnerable if you stray from what people expect and made them loyal to you. I don't think it's that big a deal, but I can see this alienating a fair amount of people.
