A guide for families & caregivers — Updated 2026
If your parent relies on supplemental oxygen and you’re hoping to take a trip together — or simply get them to a family event across the country — you’ve probably found yourself wondering whether any of this is even possible. The good news: yes, portable oxygen concentrators are allowed on most commercial flights, and millions of people travel with them every year. But there are rules, and the details matter. This guide will walk you through everything you need to know so you can plan with confidence instead of dread.
The Short Answer: Yes — With Conditions
The Federal Aviation Administration (FAA) permits FAA-approved portable oxygen concentrators (POCs) on commercial flights operating within the United States. This rule has been in place since 2005, and it was a significant victory for people who depend on supplemental oxygen. However, not every POC model is automatically approved, and every airline has its own policies layered on top of the FAA baseline. International travel adds another layer of complexity.

The key things to understand upfront:
- Only FAA-approved POC models may be used on U.S. commercial flights.
- You must notify your airline at least 48 hours before departure — many require more notice.
- You will need a physician’s statement to bring and use oxygen on board.
- Airlines cannot charge extra fees simply for bringing an approved POC.
- You cannot use liquid oxygen or oxygen tanks on commercial flights — a POC is the only accepted form of supplemental oxygen.
What Makes a POC “FAA-Approved”?
The FAA evaluates POCs based on safety criteria — primarily whether the device produces less than 5 liters per minute of continuous flow oxygen and meets electrical safety standards. Approved devices are listed in the FAA’s official guidance and are typically labeled by the manufacturer as FAA-approved. Before you purchase or rent a POC for air travel, confirm the specific model is on the FAA-approved list — this is not something to assume.
Note: The FAA approval list is updated periodically. Always verify directly with the FAA website or your airline before travel.
What Airlines Require From You
Even with an FAA-approved device, each airline has its own documentation and notification requirements. Here’s what’s typically required:
- Advance notification: Call the airline’s accessibility or special services desk — not the general booking line — at least 48–72 hours before your flight. Many airlines recommend calling as soon as you book.
- A physician’s statement: Most airlines require a signed letter from your parent’s doctor stating the medical necessity for oxygen, the prescribed flow rate, and confirming the patient can travel safely by air. Some airlines have their own specific form.
- Sufficient battery life: FAA rules require that you carry enough battery power to last 150% of the total flight time — including expected delays. This is calculated per flight segment, not just one leg of a connection.
- Seat assignment considerations: Airlines will typically not seat a POC user at emergency exit rows, and some have other seating restrictions. Confirm this when you call.
A Quick Comparison: What Varies by Airline
| Requirement | FAA Baseline | Airline May Also Require |
|---|---|---|
| Advance notice | Not specified by FAA | 48–72 hours minimum; sometimes more |
| Doctor’s letter | Not required by FAA | Almost always required by airlines |
| Battery supply | 150% of total flight time | Same, but may define “flight time” differently |
| Airline-specific form | Not required by FAA | Some airlines require their own medical form |
| Fee for POC | Airlines cannot charge for approved POC | No fee allowed under DOT rules |
Flying Internationally? Plan Extra Time
If your family is planning international travel, the rules become more complex. Foreign carriers are not subject to FAA regulations, and some countries have their own restrictions on oxygen devices. Before booking any international trip, contact the airline’s accessibility team directly and research the destination country’s aviation authority guidelines. It’s also wise to confirm what oxygen support is available at your destination in case equipment fails or needs servicing.
Tips for a Smoother Experience at the Airport
- Arrive early — TSA screening with medical equipment takes additional time.
- Carry all documentation in a dedicated folder that stays with your parent at all times.
