Portable oxygen concentrator

Question

If I travel with a portable oxygen concetrator but I am not using it on the plane does it still have to be an FAA approved device. I only use it at night with a CPAP machine.

Answer 1

does it still have to be an FAA approved device

American Airlines states :

FAA Regulations prohibit the use and transportation of other personal oxygen units, including those that contain compressed or liquid oxygen because they are classified as hazardous materials.

Delta states :

If you do not intend to use your FAA approved PAP machine during your flight, you may bring it on board and are not required to travel with 150% of battery life for the flight time. The battery must still comply with airline requirements.

United doesn't state explicitly that it must be FFA approved, but I would infer that the same rules apply to United as well

If you don’t need to use your POC during your flight, you can bring it as a carry-on or in a checked bag with the batteries removed

The TSA states :

Nebulizers, CPAPs, BiPAPs, and APAPs Carry On Bags: Yes (Special Instructions) Checked Bags: Yes (Special Instructions)

Nebulizers, CPAPs, BiPAPs and APAPs are allowed in carry-on bags but must be removed from the carrying case and undergo X-ray screening. Facemasks and tubing may remain in the case.

You may provide a clear plastic bag to place the device in for X-ray screening. A TSA officer may need to remove the device from the bag to test it for traces of explosives.

Liquids associated with nebulizers are exempt from the 3-1-1 liquids rule, in reasonable quantities. For more information, see TSA special procedures.

Devices containing lithium metal or lithium ion batteries should be carried in carry-on baggage. Most other consumer electronic devices containing batteries are allowed in carry-on and checked baggage.)
