Having a portable oxygen concentrator does not have to mean staying home. Seniors fly, cruise, drive cross-country and stay in hotels with oxygen every day. What makes those trips smooth is preparation: the right paperwork, enough battery power, a plan for charging and a backup if something goes wrong. This step-by-step guide covers the logistics of travelling by air, car, train and ship with a portable oxygen concentrator (POC). Before any trip, talk to your doctor about whether travel is safe and whether your oxygen needs change at altitude, since aircraft cabins are pressurised to the equivalent of roughly 6,000 to 8,000 feet.

Quick answer: Our top pick in 2026 is the Doctor's letter and airline form — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.

Four to six weeks before the trip

  • See your doctor and ask for a letter or form stating your oxygen needs, including flow setting, and confirming you are fit to travel. Many airlines have their own medical form.
  • Ask whether you need a higher setting during the flight or at your destination if it is at altitude.
  • If renting a POC, reserve it early, especially for holiday travel.
  • Check your destination’s electricity; most POC power supplies work on 100 to 240 volts, but you may need a plug adapter.

Flying with a POC

Airline notification

Call or check the airline’s website at least 48 hours before departure, and earlier if possible. Tell them you will use a POC on board, provide the model, and ask about their forms. Policies vary between airlines, and international or partner airlines on connecting flights may have different requirements.

Battery requirements

Airlines commonly require enough battery power for 150% of the expected flight time, including connections and ground time. For a 4-hour flight, plan for at least 6 hours of battery. Aircraft outlets may not be available or reliable, so do not count on them.

Security screening

TSA allows POCs through security. You can ask to remain connected if you cannot be without oxygen; the device can be inspected rather than X-rayed if needed. Allow extra time.

Spare batteries

Spare lithium batteries must travel in carry-on luggage, never checked baggage. Protect terminals with caps or individual bags. Batteries up to 100 watt-hours are generally allowed; 100 to 160 watt-hours usually require airline approval.

On board

The POC typically must be stowed under the seat in front during take-off and landing, so bring a cannula long enough. You may not be able to sit in an exit row.

Travelling by car

A DC adapter lets the POC run and charge from the car’s power socket while the engine is running. Keep the unit upright and secure, with air vents unobstructed, and never leave it in a hot or freezing parked car. Plan stops where you can plug in, such as restaurants. Do not smoke in the car, and keep the windows slightly open if you also carry oxygen cylinders.

Cruises, trains and buses

Cruise lines usually require advance notice, often weeks before sailing, and a medical form. Ask about outlets in your cabin and plan for shore excursions where charging may not be possible. Trains such as Amtrak allow POCs with conditions on battery capacity and advance notice; bus lines have their own rules. Always check with the specific carrier.

At the hotel

Ask for a room near the elevator and away from smoking areas. Charge batteries overnight, and keep the POC away from curtains and heaters. Let the front desk know you use oxygen in case of an emergency evacuation.

If something goes wrong

Know the signs you need help: increasing breathlessness, confusion, chest pain or bluish lips. Carry your supplier’s 24-hour number and a list of medications and diagnoses. Some manufacturers have service networks that can swap a failing unit while you travel.

FAQ

Do I need to tell the airline I am using a portable oxygen concentrator?

Yes. Most airlines require advance notice, commonly 48 hours or more, along with details of the device and sometimes a medical form. Check each airline on your itinerary.

Can I bring oxygen tanks on a plane instead?

Personal compressed oxygen tanks are generally not allowed in the cabin on commercial flights. Portable oxygen concentrators are the accepted option for in-flight use.

Bottom line

Travelling with a portable oxygen concentrator is very achievable with planning. Get your doctor’s letter, notify carriers early, carry batteries for 150% of your travel time, pack power adapters and spares, and keep your supplier’s number handy in case you need help on the road.
