What is the maximum amount of dry ice that can be included in checked baggage?

The maximum amount of dry ice that can be included in checked baggage is limited to 5.5 pounds. This regulation is in place for safety reasons, as dry ice, which is solid carbon dioxide, can produce carbon dioxide gas as it sublimates. In enclosed spaces such as the cargo hold of an aircraft, high concentrations of this gas can pose a risk to the crew and the integrity of the aircraft’s environment.

The limit ensures that there is enough ventilation and that the gas does not accumulate to dangerous levels. Airlines must also be informed when dry ice is being transported, allowing them to take necessary precautions. Understanding these regulations is vital for compliance and ensuring safety on flights that involve hazardous materials like dry ice.
