Like my title says... "Horrible, filthy, dirty, crowded"
Terminal 4 where Spirit Airlines is located and run by them is awful, the terminal is dirty and smells like crap.
The restrooms are dirty, I wonder if anybody works on maintenance on that terminal.
I can say that it has to be Spirit Airlines fault, because all the other terminals are not as bad as this one!
I forgot to mention that security sucks! slow, and crowded, and the TSA people have a bad attitude!
