If you use supplemental oxygen, the idea of a long flight can feel daunting — but flying with a portable oxygen concentrator is a well-trodden path with clear rules. Thousands of travellers do it every day. The key is that airlines, airports, and regulators have a specific system for POCs, and it works smoothly if you prepare. This guide walks through the logistics: which devices can fly, what to tell your airline, the battery maths you must get right, security screening, and using your concentrator onboard. One important note before we start: this is general travel information, not medical advice. Talk to your doctor before flying with oxygen, and confirm every detail with your airline — policies differ between carriers.
Only FAA-Approved POCs Can Fly
Not every portable oxygen concentrator is allowed on aircraft. In the United States, the Federal Aviation Administration maintains a list of POC models approved for use during flight, and airlines are only required to accept devices on that list. If you are flying outside the US, check the equivalent authority — most countries follow similar rules.
Common FAA-accepted models include the Inogen One family, the Philips Respironics SimplyGo and SimplyGo Mini, the SeQual Eclipse, and the AirSep FreeStyle series — but the list changes, so verify your exact model against the FAA’s current list before you book. The approval relates to electromagnetic interference and battery safety, not medical efficacy.
Two things to check beyond the model name. First, your POC must carry the manufacturer’s label confirming it is approved for onboard use — airlines may ask to see it. Second, the unit must be in good working order with clean filters and intact batteries. If your concentrator is old or has been repaired with non-standard parts, get it serviced before you fly.
Tell Your Airline in Advance
Under US Department of Transportation rules, airlines must allow you to bring an FAA-approved POC onboard — but they can require advance notice, and most ask for at least 48 hours. In practice, tell them the moment you book. Call the airline’s accessibility or special assistance desk (not the general reservations line) and have your flight details ready.
Most airlines will also ask for a physician’s written statement. The DOT specifies what this must cover: confirmation that you need oxygen during the flight, your prescribed flow rate, and a statement that you are able to respond to the unit’s alarms and use it properly. Some airlines have their own medical form for your doctor to complete — ask for it early, because chasing paperwork the week before you fly is miserable.
Keep copies of everything — the physician’s statement, your booking confirmation showing the POC notification — in your carry-on, not in checked luggage. If a gate agent questions the device, calm documentation ends the conversation quickly.
The 150% Battery Rule
This is the rule that catches people out. Your POC batteries must be able to power the device for 150% of the scheduled flight duration — including connections and layovers. A four-hour flight means six hours of battery. An eight-hour leg with a two-hour connection means fifteen hours of battery. Do the maths for your specific itinerary, at your prescribed flow setting — higher flow drains batteries faster.
All spare batteries must travel in your carry-on — never in checked luggage. This rule is non-negotiable. Protect the terminals of spare batteries with tape, or keep each battery in a separate plastic bag or its original packaging, so they cannot short-circuit against each other or metal objects.
Practical battery tips: fully charge every battery the night before; bring one more battery than your calculation says you need; and know your concentrator’s actual battery life at your flow setting, since manufacturer figures are often optimistic. If your POC has an AC adapter, pack it too — you can top up at the gate between flights, though you should never count on in-seat power.
Going Through Airport Security
Your POC will be screened at the security checkpoint like any other electronic device. Place it in a bin for X-ray screening, and tell the officer that you use supplemental oxygen and that the device is medically necessary — they see these regularly.
If you cannot safely disconnect from your oxygen, say so: the TSA can screen you and the device through alternative methods rather than separating you from it. You can also request a pat-down instead of the body scanner if you prefer. Spare batteries stay in your carry-on with their terminals protected; they do not need to come out of your bag, but having them easily accessible speeds things up if an officer wants a closer look.
One more tip: wear your cannula through the checkpoint if you need continuous flow, and keep a spare cannula in your personal item. Cannulas are cheap, light, and easy to lose.
Using Your POC Onboard
Once aboard, a few rules and realities. Use battery power only — do not count on in-seat power outlets, which are inconsistent, often disabled, or unsuitable for medical devices. Stow the concentrator under the seat in front of you during taxi, takeoff, and landing, as the crew will instruct; you can generally have it out and running during cruise.
A window seat is worth requesting: it keeps the unit and its tubing out of the aisle, where they would be a trip hazard for other passengers and crew. Keep your nasal cannula on for the whole flight, and bring spares. If your POC has both pulse-dose and continuous-flow modes, confirm with your doctor which to use in flight — cabin pressure is lower than at sea level, and your prescription accounts for that.
Listen to the crew. They have the final say on when the device must be stowed, and a calm, cooperative attitude gets you far more help than an argument.
Your Pre-Flight Checklist
- POC model verified against the FAA approved list; manufacturer approval label present.
- Airline notified at least 48 hours ahead; confirmation saved.
- Physician’s statement completed, with flow rate and alarm-response confirmation; copies in carry-on.
- Batteries calculated at 150% of total flight time at your prescribed flow setting, plus one spare.
- All batteries fully charged; spares in carry-on with protected terminals.
- AC adapter packed for gate top-ups; spare cannulas and tubing in personal item.
- Doctor consulted; airline policies double-checked.
Flying with a portable oxygen concentrator is routine — these rules exist precisely because so many people do it. The travellers who run into trouble are almost always the ones who skipped the battery maths or left the airline notification to the last minute. Do the preparation, and the flight itself is the easy part. Remember: this is general information, not medical advice — check with your doctor and your airline before you fly.
Flying With a Portable Oxygen Concentrator FAQ
Do I need to tell the airline I’m bringing a portable oxygen concentrator?
Yes. Most airlines require at least 48 hours’ notice under US DOT rules, and you will usually need a physician’s statement covering your oxygen needs, flow rate, and ability to respond to the unit’s alarms. Notify the airline’s accessibility desk when you book, and keep copies of everything in your carry-on.
How many batteries do I need for my POC?
Enough to power the concentrator for 150% of your total scheduled flight time, including connections — calculated at your prescribed flow setting. All batteries go in your carry-on, never in checked luggage, with their terminals protected. Bring one more battery than the maths says you need.
Can I use my POC during takeoff and landing?
Follow the crew’s instructions — they have the final say. Most airlines require the unit to be stowed under the seat during taxi, takeoff, and landing, with use permitted during cruise. Always run on battery power rather than counting on seat outlets.
Will security make me disconnect my oxygen at the checkpoint?
No. Tell the officer you use supplemental oxygen; the POC goes through X-ray screening, and if you cannot safely disconnect, alternative screening methods are available. You can also request a pat-down instead of the body scanner.
