What is the maximum amount of dry ice per container per passenger?

• A. 5.5 pounds
• B. 1 pound
• C. 10 pounds
• D. 2 pounds

Answer: (A)

The key idea is safety from gas buildup. Dry ice sublimates into carbon dioxide, and in the confined space of an aircraft cabin, too much CO2 can create a hazardous environment for passengers. Regulations cap how much dry ice a passenger can bring in one container to prevent that risk while still allowing cooling for perishables or medical items. The limit is five and a half pounds per passenger per container, which corresponds to about 2.5 kilograms. This amount provides practical cooling without risking unsafe CO2 levels. Smaller amounts may not keep items cold long enough, while larger amounts would exceed what is considered safe for cabin exposure.
