A scam, pure and simple. They simply lie about the ticket class and then leave you to sort out the details. I bought a standard economy class ticket at prices higher than others because I needed checked baggage. After lots of misdirection (and conveniently enough the 24 hour refund period) I was told i was incorrect (despite the screen shots and Just Fly's own confirmation email). A straight out hustle, and I guess not much to do about it. Hope this helps others...
