Can You Fly with an Oxygen Concentrator? TSA, FAA, and Airline Rules -

Flying with a portable oxygen concentrator (POC) can feel like a challenge if you’re not sure where to start. If you’ve ever asked yourself, Can you fly with an oxygen concentrator?, the good news is—yes, you can. But there are important rules you need to follow.

The Federal Aviation Administration (FAA), Transportation Security Administration (TSA), and airlines each have specific requirements to ensure you and your device stay safe during the flight. Whether you’re traveling within the U.S. or internationally, knowing these guidelines will make your trip much easier.

In this guide, I’ll walk you through everything you need to know about flying with a POC. If you want more tips for traveling with medical devices, check out my Flying with Medical Devices: The Ultimate Guide.

1. FAA Rules for Flying with an Oxygen Concentrator

1.1 What FAA Approval Means

The Federal Aviation Administration (FAA) regulates which portable oxygen concentrators are permitted on flights departing from or arriving in the U.S. Unfortunately, many travelers assume that because a POC is portable, it must be flight-ready. Unfortunately, that’s not always the case.

Not all POCs are approved for in-flight use.

If your device isn’t on the FAA Approved Portable Oxygen Concentrators List., you may not be allowed to bring it on board or use it during the flight. Why? Because FAA approval ensures the device is safe for air travel and won’t interfere with the aircraft’s systems.

1.2 How FAA Rules Apply

On domestic flights within the United States, any U.S.-based airline must allow the use of an FAA-approved POC, as long as you meet their documentation and battery requirements.
On international flights, rules can vary. Some foreign airlines recognize FAA approval, while others follow different regulations. It’s important to confirm the airline’s policy ahead of time, especially when flying outside the U.S.

KEEN TIP: Even if you’re flying with an FAA-approved POC, you’ll still need to notify your airline in advance and follow their guidelines.

2. Notify Your Airline Early

2.1 When to Notify the Airline

Most airlines require at least 48 hours’ notice if you plan to use your POC on the plane. However, I recommend contacting them as soon as you book your ticket—especially if you’re flying internationally or have a connecting itinerary.

My experience: I typically download the app for the airline I am flying on and via text am able to get everything done much more easily than when I call and have to wait on hold. A robot or bot greets you but I text “I want an agent” and if that doesn’t work I will confuse the bot with a long-winded sentence. At that point, the silly thing says “would you like an agent?” and I get a live, human airline rep pretty quickly. I can then ask my questions, get their confirmations and it’s all part of a record. I also request that they make a notation on my ticket and when I go online a few hours later to check it, the info about a medical device is right there in my passenger details.

Keep in mind, each airline has its own process for approving medical devices onboard. Some may ask you to complete forms, while others might require a medical statement from your doctor. Getting this paperwork in order early can save you from last-minute stress at the airport.

KEEN TIP: Reach out to the special assistance department or medical desk of your airline as soon as possible. It can take time to process approvals, and earlier notice increases your chances of getting your preferred seat.

2.2 What Airlines Need to Know

Be prepared to provide the following information when you notify your airline:

The make and model of your POC
Confirmation that it appears on the FAA-approved list (here’s the link again: FAA Approved Portable Oxygen Concentrators)
Details about your battery type and capacity (especially if using lithium-ion batteries)
Your doctor’s note, if requested (more on this in Section 6)
Signed medical forms required by the airline (some have their own versions you’ll need to complete)

2.3 Get Written Confirmation

Generally you can print out your ticket details showing that you are carrying a medical device but when you are texting with or speaking to an airline agent, you can always request that they email you a confirmation as well.

KEEN TIP: I recommend printing two copies of your approval—one to keep with you and one to pack as a backup. If the airline can’t email you, ask them to send it via traditional mail. Having it in writing can help smooth over any confusion at check-in or boarding.

3. Battery Requirements for Flying with a POC

Please check out our guide to flying with power banks to charge your medical devices.

3.1 Understanding FAA Battery Rules

The FAA has clear regulations about battery requirements when flying with a portable oxygen concentrator (POC). You must bring enough battery power to cover at least 150% of your total expected flight time. This includes the flight itself, layovers, and any unexpected delays.

For example, if your total travel time (from gate to gate) is 8 hours, you’ll need at least 12 hours’ worth of battery power for your POC. It’s better to overestimate your needs, especially on longer trips or flights with multiple connections.

KEEN TIP: Always calculate for potential delays. I’ve seen travelers run into trouble because they didn’t have enough battery power during unexpected layovers or tarmac delays.

3.2 TSA and Airline Policies on Batteries

In addition to FAA rules, TSA and airlines have specific guidelines for carrying spare batteries, especially lithium-ion batteries, which are commonly used in POCs.

Here’s what you need to know:

Lithium-ion batteries rated up to 100 watt-hours (Wh) are generally allowed in carry-on luggage with no airline approval required.
Batteries between 100 Wh and 160 Wh typically require airline approval and are limited to two spare batteries per passenger.
Batteries over 160 Wh are usually not allowed on passenger aircraft.

All batteries should be:

Stored in carry-on luggage (not checked bags)
Individually protected to prevent short circuits (use the original packaging, place tape over the terminals, or use a battery case)

KEEN TIP: Check your battery’s watt-hour (Wh) rating—it’s usually printed on the label. If it’s not listed, you can calculate it by multiplying volts (V) by amp hours (Ah):
Wh = V x Ah

3.3 How Many Batteries Should You Bring?

Most POC users bring at least two spare batteries in addition to the battery installed in the device. If you’re on a long-haul flight or traveling internationally, consider bringing more than two spares, if your airline allows.

KEEN TIP: Keep your spare batteries in your carry-on, and make sure they are individually protected (original packaging, battery cases, or taped terminals) to avoid short circuits.

4. Choosing the Right Seat for Comfort and Accessibility

4.1 Why Seat Selection Matters

When you’re flying with a portable oxygen concentrator (POC), your seat choice isn’t just about getting a window view or extra legroom—it can make managing your device much easier.

For most travelers with a POC, an aisle seat near the front of the plane is the best option. It allows easier access to the restroom, offers more flexibility in case you need assistance, and makes handling your POC less complicated, especially on longer flights.

Some airlines assign specific seats for passengers traveling with medical devices. If you require in-seat power, these seats are often concentrated in specific rows.

KEEN TIP: When booking, you can ask if your seat has in-seat power, but plan as though you won’t have access to it. Even when outlets are available, power output may not be reliable for medical devices.

Even if you secure a seat with an outlet, FAA and airline policies require you to have enough battery life to power your POC for 150% of the total flight time, without relying on the plane’s electrical system.

KEEN TIP: Print a copy of your medical documentation and FAA approval letter to bring to the airport. It helps explain your request clearly and shows that you’ve done the necessary preparation.

5. TSA Security Screening with a Portable Oxygen Concentrator

5.1 What to Expect at TSA Checkpoints

When flying with a portable oxygen concentrator (POC), you will need to go through the Transportation Security Administration (TSA) checkpoint just like any other traveler. But there are a few extra steps for travelers carrying medical devices.

TSA requires that all POCs be screened, either by an X-ray machine or manual inspection. If your device can’t fit through the X-ray, or you prefer not to put it on the belt, you can request a manual inspection instead.

5.2 How to Prepare Your POC for Screening

When you reach security:

Inform the TSA officer immediately that you are traveling with a portable oxygen concentrator.
Have your doctor’s letter and FAA approval documentation ready in case they ask for it.
Be ready to remove any accessories from your POC bag (extra batteries, tubing, or chargers) for separate screening.

TSA officers may swab your POC and batteries to check for traces of explosives. This is standard procedure and usually takes only a few minutes.

KEEN TIP: The TSA officer should change gloves and use a fresh swab before inspecting your device. This helps avoid contamination and reduces the risk of false-positive readings.

5.3 Can You Request a Private Screening?

Yes. A private screening will still involve swabbing and possibly a physical inspection of your device, but it can be done in a less public setting.

KEEN TIP: Be polite but firm about how you want your device handled. TSA officers are required to follow protocols, but they can also accommodate reasonable requests for additional care.

6. Customs and International Travel with a Portable Oxygen Concentrator

6.1 Customs Rules When Traveling Internationally

If you’re flying internationally with a portable oxygen concentrator, it’s important to understand that customs regulations can vary from country to country. While the FAA rules cover U.S. flights, they don’t apply once you land overseas.

Some countries require special permits or documentation to bring medical devices like POCs through customs. In some cases, officials may ask for proof that your POC is for personal medical use and not for resale or commercial purposes.

Be prepared to declare your POC and show documentation to customs officials upon arrival.

KEEN TIP: Visit the U.S. embassy website for the country you’re visiting before your trip. They usually provide detailed information on customs requirements and health regulations for travelers bringing medical equipment.

6.2 Documents to Bring for International Customs

Here’s a checklist of documents to have ready at customs when traveling with a POC:

A doctor’s letter explaining your need for oxygen therapy and your use of a portable oxygen concentrator
Your prescription for the POC
Proof that your device is FAA-approved (or approved by the aviation authority in the country you are visiting)
Translated copies of all documents, especially if you’re traveling to a non-English-speaking country
Any permits required by the destination country for medical equipment (check with the embassy)

KEEN TIP: Have multiple copies of these documents. Keep one set in your carry-on and a backup in your personal bag. I also recommend having copies on your phone (simply use your camera to take photos of each document).

6.3 Understanding Local Laws and Airline Rules Abroad

Some countries may restrict the public use of oxygen devices or require registration of medical equipment upon arrival. Additionally, if you’re flying on a foreign airline during your trip, they may not follow FAA regulations. Each airline may have its own rules about POC approval, battery capacity, and onboard usage.

KEEN TIP: Just as you do when you fly domestically, contact your foreign airline’s medical assistance department before booking. Confirm their policy on portable oxygen concentrators, batteries, and seating arrangements. Request written approval.

6.4 International Battery Guidelines

Battery restrictions can differ outside the U.S. While FAA and TSA rules apply to U.S.-based flights, other countries may have their own standards for lithium-ion batteries. Your airline or the embassy at your destination can help with this.

For example:

Some countries may limit the number of batteries you can bring.
Others may have lower watt-hour limits or require additional labeling.
In some regions, battery disposal laws are strict—if you need to replace a battery while traveling, you may be required to dispose of old batteries at certified locations.

6.5 Medical Facilities and Emergencies Abroad

Research medical facilities at your destination that can provide oxygen therapy services, just in case your POC stops working or batteries fail.

KEEN TIP: Carry a list of local hospitals and clinics, along with emergency contact numbers. Having a backup plan gives you peace of mind.

7. In-Flight Use and Comfort Tips with a Portable Oxygen Concentrator

7.1 Using Your POC During the Flight

Once you’re onboard, you’re allowed to use your FAA-approved portable oxygen concentrator throughout the entire flight, including taxi, takeoff, cruising, and landing. The crew may briefly check to ensure your device is properly stowed and doesn’t block the aisle or emergency exits. Again, if you are on an international flight our FAA rules don’t apply. Get clarity on whether you can use it onboard beforehand.

Here’s what you need to do:

Keep your POC under the seat in front of you when not in active use.
Make sure tubing and cords are tucked away safely and don’t create a tripping hazard for you or other passengers.
Your device must operate quietly and not disturb others onboard.

KEEN TIP: If you’re worried about the tubing tangling or getting caught, bring extra tubing clips or fasteners to keep everything neatly secured.

7.2 Managing Battery Power During the Flight

Use fully charged batteries as your primary power source.
Periodically check battery levels during the flight to ensure you’re never running low.
If your POC allows, rotate between batteries during longer flights to keep spares as fully charged as possible.

KEEN TIP: Store spare batteries in an easy-to-reach compartment of your bag so you can swap them out without fumbling in overhead bins.

7.3 Communicating with Flight Crew

Let a flight attendant know you’re traveling with a POC when you board. If there’s an emergency or you experience issues with your device, they’ll be aware of your situation and ready to assist.

Inform them if you experience any breathing discomfort.
Know where the emergency oxygen is located (some airlines carry additional oxygen bottles, but they may not be available for personal use unless there’s a medical emergency).

KEEN TIP
Always advocate for yourself. If you need something, such as extra water or assistance getting up, don’t hesitate to ask the crew.

8. Arrival and Post-Flight Tips When Traveling with a Portable Oxygen Concentrator

8.1 After You Land

Once you arrive at your destination airport:

Continue using your POC if needed, but make sure it stays clear of walkways and exits as you disembark.
If you arranged wheelchair assistance or special services through the airline, check in with the flight crew before landing so ground staff can be ready to assist you at the gate.
Some airports are larger than others, so factor in additional time to navigate the terminal—especially if you have layovers or need to collect checked luggage.

KEEN TIP: At your arrival gate, ask airport staff about the quickest route to immigration and customs which you will have to clear before leaving the airport. Many airports offer special assistance lanes, which can speed up the process.

8.2 Customs and Immigration Procedures

Be prepared to declare your portable oxygen concentrator on your customs form, if required.
Some countries ask travelers to declare any medical equipment upon entry. Check the country’s requirements before your trip by visiting the U.S. embassy website or the country’s customs agency website.
Keep your documentation easily accessible. This includes a letter from your provider explaining the need for the device, your POC’s FAA approval information, and, for some destinations, translated versions of these documents.

8.3 Inspecting Your POC and Batteries After Arrival

After a flight, it’s a good idea to give your equipment a quick check:

Inspect your POC and accessories for any visible signs of damage from the flight.
Confirm that your spare batteries and cables are still secure and functioning.
If your batteries are running low after extended use during travel, find a charging station at the airport or plan to recharge them when you arrive at your accommodations.

KEEN TIP: Bring a universal power adapter if traveling internationally, as electrical outlets and voltages differ by country.

8.4 Plan for Ground Transportation

Whether you’re catching a taxi, shuttle, or ride service, make sure your POC and carry-on luggage are easily accessible for the next leg of your journey.

If you’ve pre-arranged transportation with special mobility accommodations, confirm the pickup point at the airport ahead of time.
Some international airports are large, so verify where your transportation will meet you—whether it’s curbside or at a designated area.

KEEN TIP: Save the contact information for your hotel, travel coordinator, or transportation service in your phone or written down in case you need directions or assistance upon arrival.
