Recently, I was forced to connect through Miami International Airport (MIA). For most people who fly to and from Latin America and the Caribbean, MIA is the departure point and the first port of entry into the United States. If you are traveling on American Airlines, you will most likely be in Terminal D, a newish terminal with 60 gates than probably covers nearly a mile and serves American flights exclusively. On both the outbound and inbound legs of my journey I had about three hours to spend in Terminal D. My experience shows me that MIA views customers (passengers) as a source of revenue--a cash cow. All the food is overpriced. A slice of pizza is $5. A bagel sandwich is $8. Things that would cost half as much out on Main Street. Water is $3.  There's shopping at MIA, Thomas Pink and Burberry and of course Duty Free. Duty Free is one of the biggest scams at the airport--all it means is that you won't pay taxes on the item, but the store is free to charge what it likes on it.
