I have traveled to many airports in the world and MIA falls into the very worst airport I have ever been in. As the gateway to South American they feel they can treat people rudely and no one will complain. It has taken me up to 4 hours to clear immigration. I no longer book direct international flights (it is faster to have a layover than wait for immigration in MIA). Once you clear immigration don't expect the airport to make any sense, it is poorly labeled. There are not even signs at the baggage carosells that tell which flight the lugage has come from! If you finally escape the airport have fun with the lack of clear signs directing you to South beach (the same goes with finding the airport). Best of luck at MIA.
Pros: it is an airport
Cons: lack of signage, immigration
