Few things in this world are universal.
There are some exceptions: gravity makes things fall-down-and-go-boom, holding your breath past turning purple isn’t smart, and eating every once in a while is good for the body.
Also: flying on Spirit Airlines sucks out loud.
Sure, the initial flight charges are nice, but once you get nickel-dimed, you may as well be flying first class on a private jet. So, if you were the PR person for this airline of piss and vinegar evocation, what would you do?
Embrace the hate? They did that, and it worked.
