Can I pack carbonated beverages or soda in my checked bag? Carbonated beverages are allowed in checked bags, but they may explode due to changes in air pressure. Carbonated beverages are not allowed in carry-on luggage because bottles and cans are larger than 3.4 ounces.

Generally, no, you cannot bring canned beverages through a TSA security checkpoint in your carry-on luggage if they exceed the 3.4-ounce (100ml) limit. Standard soda or beer cans are typically 12 ounces (355ml), which violates the "3-1-1" rule for liquids, gels, and aerosols. If you have a can in your bag, security will require you to either drink it, toss it, or place it in your checked luggage. However, in 2026, many major UK and European airports have replaced the 100ml rule with 2-liter limits thanks to new CT scanners; at these specific locations, you can leave full cans in your bag. In the U.S., you must wait until you are past security to purchase canned drinks at an airport kiosk, which you can then freely take onto the plane. The only exception is if the can is completely empty, in which case it is treated as a solid metal container.
