I've seen many people mention "duty free" when talking about liquor being purchased at the airport in Belize City, and then brought with you to the island. What exactly is duty free? I see the store boxes it up for you to take, and it doesn't count against your luggage weight, but I've also seen it can be a carry on. Does that mean I will now need to check my (original) carry on for the flight to the island? I'm confused. Please help!
