Cuba charges CUC25 departure tax on international flights. Cuban check-in staff often scam foreigners by attempting to charge an excess baggage fee where none should apply. Know your legal allowance (which varies between airlines). Try to use a counter with a visible scale screen and check that it is properly zeroed before your bags are put on.
Cuba prohibits the export of valuable antiques and art without a license.
