Although going to Cancun is probably the most fun you can have with your clothes on, going through airport security can be a challenge. The good folks at TSA are gradually getting their act together, and it seems like it gets easier to pass through airport secirity with each passing month.
On your trip to Cancun you will experience airport security at you home airport and also when departing Cancun International Airport (CUN). If you think the Mexicans will be lax in their responsibilities of airport security...think again. You will probably experience very diligent security efforts at both airport locations, including the Cancun end. Mexican officials take airport security very seriously.
When getting ready to pack your bags for your Yucatan adventure it is a good idea to plan ahead for airport security. As a general rule the good folks at the security checkpoints will not allow you to pass through into the terminal gate areas with anything on your person or in your carry on luggage that could be used as a weapon. They are a little less strict on items that are packed in your luggage that is being checked in. Obviously all types of explosives and flammable items are forbidden in the luggage area and in the main cabin.
