Can you take oxygen on a plane?

Reviewed by the AirAmbulance.org editorial team · Updated 13 November 2026 · Editorial policy

You can't bring your own compressed or liquid oxygen tank on board, but most airlines allow approved portable oxygen concentrators (POCs) if you follow the battery and notice rules.

Portable oxygen concentrators (POCs)

• US rules allow passengers to use an approved portable oxygen concentrator on board. Check the label or manufacturer's statement that it meets FAA requirements.
• Bring enough fully charged batteries to power the POC for at least 150% of the expected flight duration (for example, 15 hours of battery for a 10-hour flight).
• Airlines may require advance notice (up to 48 hours) and a physician's statement for POC use on board. Ask the airline when you book.

Oxygen tanks

• Passengers can't bring their own compressed or liquid oxygen tanks on board.
• Some airlines provide medical oxygen on board for a fee; others don't. Ask the airline's medical desk.

Before you fly

• Ask the doctor whether you are fit to fly and what oxygen flow you'll need at altitude.
• Arrange oxygen at your destination and for any connections.
• If you need more oxygen than a POC can provide, or need monitoring, a medical escort or air ambulance with medical oxygen is the safer option.
