Get Delta Airlines Physician's Statement

Obtaining oxygen for air travel — The Federal Aviation Administration (FAA) does not allow travelers to carry their own oxygen tanks or liquid oxygen aboard commercial aircraft. Instead, most patients can use a FAA Department of Transportation approved battery-powered portable oxygen concentrator.

You must have a signed, written Medical certificate for Portable Oxygen Concentrator use. We suggest you print the Medical certificate for POC use form available on our website.

You may bring personal medical oxygen cylinders through the screening checkpoint and into the gate area. However, personal medical oxygen cylinders are not permitted in the aircraft cabin as they are considered hazardous materials by the Federal Aviation Administration.
