Carry-on Baggage
- Dry ice in carry-on baggage is regulated just a little bit differently than checked baggage. Here is the list of requirements for carry- Ons:
- Dry ice must be placed in packaging that is allowed to release carbon dioxide. Again, if the dry ice is in an air tight container, it could explode. Having things explode on a plane is probably not a good idea.
-You are limited to 4.4 pounds of dry ice per carry-on.
-Every package of dry ice must be marked "CARBON DIOXIDE SOLID" or "DRY ICE".
-Every package of dry ice must also be marked with the net weight of the dry ice or an indication that the dry ice is 4.4 pounds or less.
