The Caribbean Airlines Baggage Fees policy has an easy-to-understand baggage cost policy that helps to relieve some of the tension out of vacation planning. You may travel with peace of mind while you get ready for your trip because most international flights allow you to check one bag for free. There can be extra charges if you need to bring more luggage or if your bags are too big. To make sure there are no surprises when you go to the airport, it is a good idea to check the baggage regulations that apply to your particular aircraft. Different baggage policies apply to domestic flights within the Caribbean and costs may apply even for the first checked bag. Caribbean Airlines lets passengers bring one carry-on bag in addition to checked luggage so you may keep your essentials with you while flying.
