So the JC Penny’s effect is a phenomenon in consumer psychology where consumers react negatively to something even though it is better to them but it doesn’t feel better.
It is named after the store JC Penny’s who got rid of sales and instead lower prices to what they would be on sale all the time. This was better for the consumer but consumers liked sales so they hated it.
They’re also removing the free checked bags AFAIK which is probably the real reason people chose them. I have had nothing but bad experiences with Southwest and can’t stand them any longer. The seat free-for-all was also shitty too and I’m glad to see it go.
So what’s left to differentiate them? That they don’t serve food other than pretzels? That’s a big selling point?
I imagine just competing on price and routes. It’s not as if many other airlines will treat you any better.
