The ABC Charters service that flies between Miami and Cuba contracts to
American Airlines and the one-hour flight is aboard an American Airlines
737 airplane with an American Airlines crew.

Flying into Cuba, there is a $20 checked bag fee plus a $2 per pound fee
for any weight over 44 pounds for all checked AND carry-on bags. Try
to make that limit carrying cameras and lenses. Somehow, there is
no bag fee for the return trip to Miami.
