If https://inogen197.bloggersdelight.dk/2024/02/14/portable-oxygen-concentrators-could-keep-you-mobile-even-with-chronic-bronchitis/ used an oxygen concentrator a decade 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 now you can travel anywhere!
Airplane travel
The Federal Aviation Administration, or FAA, has ruled that all passengers who require oxygen should be permitted to bring FAA-approved portable oxygen concentrators on all U.S. aircraft with more than 19 seats. Foreign airlines must 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 some 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.
We 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 you may don't use a wheelchair, you'll appreciate getting the extra space for the oxygen equipment.

Car travel
Who doesn't love an old-fashioned road trip? The majority 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.
