If you used an oxygen concentrator 10 years ago, you know what size and heavy they used to be. Thank heavens times have changed. Today's portable models are so small and light that now you can travel anywhere!
Airplane travel

The Federal Aviation Administration, or FAA, has ruled that all passengers who require oxygen should be allowed to bring FAA-approved portable oxygen concentrators on all U.S. aircraft with an increase of than 19 seats. Foreign airlines must also allow POC on all flights to and from U.S soil. Most portable oxygen concentrators are actually approved by the FAA, like the Inogen One, Inogen One G2, Respironics EverGo, SeQual Eclipse, DeVilbiss Igo and some others.
Train travel
Amtrak also allows medically necessary oxygen equipment onboard. You just need to provide them with 12 hours' advance notice and assure them you have the needed equipment, including adequate battery back-up. Call 1-800-USA-RAIL.
We recommend you reserve a Superliner Accessible Bedroom for your Amtrak trip. They are lower-level rooms with space for a wheelchair and two adults. Although you may avoid a wheelchair, you'll appreciate getting the extra space for your oxygen equipment.
Car travel
Who doesn't love an old-fashioned road trip? Most of today's portable concentrators come with a DC power that plugs into your car's cigarette lighter outlet. This makes it easy to power and recharge your concentrator regardless of just how long your drive.
