There is a $29 departure tax, payable in U.S. dollars, colones, or by credit card. Make sure to pay the departure tax first before lining up at the check-in. Paying by U.S. dollars or colones is recommended because your credit card will be charged as though it is a cash advance, resulting in interest charges if you don't pay your credit card balance right away.

 After going through airport security, note that you will not be able to take it on board the airplane so buy only what you can consume prior to boarding.
