If you require oxygen, it is important to plan ahead when travelling by air. While some airlines offer in-flight oxygen for a fee, this is not guaranteed and often requires advance notice and paperwork from your doctor. Passengers are not allowed to carry their own oxygen cylinders on their person, in carry-on baggage, or in checked baggage. The only oxygen equipment allowed on an airplane is a portable oxygen concentrator (POC), which can be rented or purchased. These devices run on battery packs, can be recharged, and must have enough battery time to cover 150% of the flight time. It is important to research the specific airline's regulations and plan accordingly when travelling with oxygen.

What You'll Learn

Oxygen cylinders cannot be carried in checked or carry-on baggage on planes
Passengers who require oxygen during their flight must use a Portable Oxygen Concentrator (POC). POCs are battery-powered devices that can be recharged or plugged into the wall or a cigarette lighter in a car. They can be purchased or rented from various oxygen suppliers and websites such as OxygenToGo. Airlines may require a doctor's letter to verify the need for a POC on the plane.
While airlines are allowed to carry a passenger's oxygen cylinder in the aircraft cabin, the passenger cannot use it themselves. This is because it requires special overpack, written pilot notification, and additional hazmat training and manual documentation. As a result, most U.S. airlines do not offer this service.
Products such as "canned oxygen," "recreational oxygen," and "flavoured oxygen" are also prohibited on flights.

Portable oxygen concentrators (POCs) are allowed on planes
To bring a POC on board, you must inform your airline ahead of time and follow their specific instructions. Some airlines may require a doctor's letter or prescription to verify your need for oxygen. It is also important to ensure that your POC meets the acceptance criteria established by the Federal Aviation Administration (FAA). These criteria include marketing the device legally in the United States in accordance with FDA requirements. Additionally, the POC may need to bear a label indicating its conformance with the acceptance criteria.
It is recommended to carry several extra battery packs for your POC, as FAA regulations require enough battery time to cover 150% of the flight time. You can also carry an extra three-way plug for recharging your POC in the airport. When changing batteries, ensure that your settings on the concentrator remain the same to avoid a quick depletion of the newly inserted battery.
While POCs are allowed on planes, the final decision on whether an item is permitted through the checkpoint rests with the TSA officer. Therefore, it is essential to check with your airline and the TSA for the most up-to-date information and requirements for travelling with a POC.

Airlines are not required to provide oxygen
While commercial airlines must maintain a cabin pressure altitude of no more than 8,000 feet, passengers requiring oxygen may need to make special arrangements. Passengers are not permitted to bring their own oxygen supply, including compressed oxygen or liquid oxygen, onto the aircraft in their carry-on or checked baggage. "Canned oxygen," "recreational oxygen," and "flavoured oxygen" are also prohibited.
Although airlines are allowed to carry a passenger's oxygen cylinder in the aircraft cabin, the passenger cannot use it due to safety concerns. This requires a special overpack, written pilot notification, and additional hazardous materials training and manual documentation. As a result, most US airlines do not offer this service.
Passengers requiring oxygen therapy must bring a portable oxygen concentrator (POC), which is the only permitted oxygen equipment on an airplane. POCs can be purchased or rented from various suppliers, and passengers must notify their airline ahead of time. Airlines are not required to provide oxygen, and many do not offer this service. Therefore, it is the responsibility of the passenger to ensure they have the necessary equipment and documentation, such as a doctor's letter, to verify the need for a POC on the plane.
It is important to note that POCs must have enough battery time to cover 150% of the flight time, and passengers should carry extra battery packs and a three-way plug for recharging during layovers. These devices can be recharged at airports and plugged into the wall or a cigarette lighter in a car. Additionally, passengers should allow extra time for check-in and refer to their airline's website for accepted POC manufacturers and brands.

You must notify the airline in advance if you need oxygen
If you require oxygen during your flight, you must notify the airline in advance. This is because the only oxygen equipment allowed on an aircraft is a Portable Oxygen Concentrator (POC), which you must bring with you. Airlines are not required to provide oxygen service and many do not. Therefore, you must notify the airline in advance to ensure that you are permitted to bring a POC on board.
Each airline has specific passenger regulations that must be followed. For example, United Airlines requires a minimum of 48 hours' advance notice that a passenger will bring a POC on board. Meanwhile, Hawaiian Airlines requires passengers with a POC to notify the reservations department at least 48 hours before their flight and check in no later than one hour before the minimum check-in time.
To satisfy airline rules, it is important to call the airline in advance and use a POC that they have approved. Many airlines list accepted manufacturers and brands on their websites. You may also need to submit a form signed by a healthcare provider. Additionally, some airlines may request documentation from a licensed physician to confirm your ability to fly without medical oxygen. Therefore, it is important to check with your healthcare provider to ensure that it is safe for you to fly with your specific oxygen needs.
When travelling with a POC, it is important to bring several extra battery packs. FAA regulations require enough battery time to cover 150% of the flight time. You should also allow plenty of extra time for check-in and carry a prescription or letter regarding your need for oxygen, signed by your doctor.

You may need a doctor's letter to verify the need for oxygen
If you need to use oxygen during a flight, you must bring a portable oxygen concentrator (POC) with you. POCs are the only oxygen equipment allowed on an airplane. Airlines are not required to provide oxygen service, and many do not.
To verify the need for oxygen, you may need a doctor's letter or prescription. This is because some airlines will require a doctor's letter to verify the need for a POC on the plane. Additionally, every airline has rules about flying with oxygen, and failure to comply with these rules can result in the airline refusing to allow you to board. Therefore, it is important to do your research about the airline ahead of time and make arrangements with the airline well in advance. Many airlines list the accepted POC manufacturers and brands on their websites.
Furthermore, for foreign flights, you will often need a more elaborate form called a Medical Information Form (MEDIF). It is not unusual for an airline to refuse a MEDIF from another airline, even if the forms are identical except in appearance. If you are a frequent traveler, you might consider printing out and completing forms for the airlines you usually fly and asking your pulmonary doctor to sign them. Most airlines are okay with forms filled out within a year.
Before flying, it is important to confirm with your healthcare provider that it is safe for you to fly and to determine if your oxygen flow needs to increase during the flight. Your doctor may order a High-Altitude Simulations Test (HAST) or an altitude simulation test to help determine your prescription for flying. A simple pulse oximeter reading while you are at high altitude, at rest, and during activity can also determine if oxygen is needed at altitude.
