If you used an oxygen concentrator 10 years ago, you know what size and heavy they was previously. Thank heavens times have changed. Today's portable models are so small and light that you will travel anywhere!
Airplane travel
The Federal Aviation Administration, or FAA, has ruled that passengers who require oxygen should be allowed to bring FAA-approved portable oxygen concentrators on all U.S. aircraft with more 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, including the Inogen One, Inogen One G2, Respironics EverGo, SeQual Eclipse, DeVilbiss Igo and a few others.

Train travel
Amtrak also allows medically necessary oxygen equipment onboard. You just need to give them 12 hours' advance notice and assure them you have the needed equipment, including adequate battery back-up. Call 1-800-USA-RAIL.
portable oxygen machine recommend you reserve a Superliner Accessible Bedroom for the Amtrak trip. These are lower-level rooms with space for a wheelchair and two adults. Although

Car travel
Who doesn't love an old-fashioned road trip? Most of today's portable concentrators have 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.
