Why not just go X? It's only 5.5 hours?
Did someone hack your account?
When I go to MIA I have a hard time settling for Y. When a flight is more then 4.5 hours I'd redeem for J.
Well, my father just flew LGA-ATL in F on a paid ticket, long story short, they did not have a seat for him in F and he seat in Y. He whats app'd me the entire flight how terrible it is....
