Medical oxygen, recreational oxygen

Passengers may not carry their own oxygen (compressed oxygen or liquid oxygen) in checked baggage, in carry-on baggage or on their person. Products such as "canned oxygen," "recreational oxygen" and "flavored oxygen" are also prohibited.

Compressed oxygen used in the aircraft cabin must be provided by the airline in accordance with 14 CFR 121.574 or 14 CFR 135.91.

Contact your airline for instructions on arranging oxygen service.

Airlines are not required to provide oxygen service and many do not.

Passengers may carry portable oxygen concentrators (POCs). See separate entry in this table.

NOTE: The following information is offered for informational purposes, check your airline's policy.

Airlines are allowed to carry a passenger's oxygen cylinder in the aircraft cabin in accordance with 49 CFR 175.501(e) but the passenger cannot use it. However, because a special overpack, written pilot notification, and additional hazmat training and manual documentation are required, most (if not all) U.S. airlines do not offer this service. Check with your airline before planning on carrying your own oxygen cylinder to your destination.
