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.

* When a passenger has one cylinder of compressed medical oxygen (size limit: 1000 L or 34 cubic feet) that is needed for personal medical use at destination, it may be carried (not used) in the passenger cabin if it is properly stowed by airline personnel in accordance with 49 CFR 175.501(e). Because a special overpack and written pilot notification are required, many airlines are not prepared to offer this service. Check with your airline before planning on carrying your own oxygen cylinder to your destination.
