Dry ice as an excellent alternative to ice packs for transporting food items, so you might be wondering if you can bring it on a plane.
According to TSA regulations, you can bring dry ice on a plane in both your carry on and checked bags, but you should check with the airline to make sure that it will be okay.
Airline Regulations
- Alaska Airlines: Alaska Airlines allow you to pack dry ice up to 5.5 lbs/2.5 kg in both your carry on and checked bags, though only on flights 001-1999, 2000-2999, and 3300-3499.
- American Airlines: American Airlines allow you to travel with dry ice up to 5.5 lbs/2.5 kg as a carry-on.
- Delta: Delta allow you to travel with dry ice packages in amounts of 5.5 lbs. (2.5 kg) in carry-on or checked baggage.
- JetBlue: JetBlue allow you to travel with dry ice up to 5.5 lbs/2.5 kg as a carry-on.
- Spirit: Spirit allow you to travel with dry ice up to 5.5 lbs/2.5 kg as a carry-on.
