- Battery Rule: 150% of total travel time (flight + layovers + delay buffer)
- Carry-On Status: POCs are assistive devices; they do NOT count as carry-on luggage

- Every POC at MCS: All 11 models sold by Main Clinic Supply are FAA-approved
If you use supplemental oxygen and want to travel by air, you need an FAA-approved portable oxygen concentrator. Federal law protects your right to fly with one, but understanding the specific rules, requirements, and your rights makes the process smooth and stress-free.
This guide explains exactly what FAA approval means, lists every approved model available at Main Clinic Supply with travel-relevant specifications, and walks you through airline requirements step by step.
What "FAA-Approved" Actually Means
Prior to May 2016, the FAA approved portable oxygen concentrators on a case-by-case basis through Special Federal Aviation Regulation (SFAR) No. 106. Each manufacturer had to petition the FAA to add their specific model to an approved list. This created confusion and delays as new models entered the market.
In May 2016, the FAA replaced this process with universal acceptance criteria. Now, any POC that meets these criteria and bears the required manufacturer's label is automatically approved for use on all U.S. commercial flights. Airlines no longer need to check a specific approved model list; they only need to verify that the device bears the compliance label.
FAA Acceptance Criteria
Under 14 CFR Part 121.574, a portable oxygen concentrator is approved for aircraft use if it meets all of the following:
- The POC is legally marketed in the United States in accordance with FDA requirements (21 CFR).
- The POC does not radiate radio frequency emissions that interfere with aircraft systems.
- The POC bears a permanent label on its exterior containing the certification statement (in red lettering): "The manufacturer of this POC has determined this device conforms to all applicable FAA acceptance criteria for POC carriage and use on board aircraft."

Airline Requirements for Oxygen Users
- Advance notice: Notify your airline 48-72 hours before departure. Most airlines have an online form or dedicated phone line for medical equipment notifications.
- Physician's letter: A signed statement from your doctor confirming your oxygen prescription, flow settings, ability to respond to alarms, and whether oxygen is needed for all or part of the flight.
- Battery capacity: Sufficient charged batteries for 150% of total travel time.
- Spare battery handling: All spare batteries must be in carry-on baggage with terminals covered or taped to prevent short circuit. Never check batteries.
- Seating restrictions: You may not sit in an exit row while using a POC. Request a seat with a power port when booking.
- Stowage: During flight, your POC should be under the seat in front of you or on your lap. It must not block the aisle or any emergency exit.
Battery Requirements
The FAA's 150% rule is the most important number for flight planning. Calculate your total travel time (flight + layover + boarding + delay buffer), multiply by 1.5, and ensure your combined battery capacity at your prescribed flow setting exceeds that number.
- Flight: 4 hours
- Layover: 2 hours
- Boarding/deplaning: 1 hour
- Delay buffer: 1 hour
- Total travel time: 8 hours
- 150% requirement: 12 hours of battery at your prescribed setting
Your Rights Under the Air Carrier Access Act
The Air Carrier Access Act (14 CFR Part 382, Section 382.133) establishes clear protections for oxygen users:
- Airlines must permit the use of FAA-approved POCs on all flights (aircraft with 19+ seats).
- Your POC is an assistive medical device and does not count toward carry-on limits.
- Airlines cannot charge extra fees for carrying your POC, batteries, or accessories.
- Airlines cannot require you to rent oxygen equipment from a specific vendor.
- If an airline denies your approved POC, request to speak with their Complaint Resolution Official (CRO) on-site, or file a complaint with the U.S. Department of Transportation.
Best POCs for Air Travel
For most travelers, we recommend the Inogen Rove 6 (4.8 lbs, settings 1-6, up to 13 hours battery). For users needing settings 1-4 who want the absolute lightest unit, the Inogen Rove 4 (2.8 lbs) is the best choice. Both fit easily under an airline seat and operate quieter than a library.

Are all portable oxygen concentrators FAA-approved?
No. Only POCs meeting FAA acceptance criteria with the required compliance label are approved. Older or non-compliant models may not be permitted on aircraft.
Can airlines refuse my FAA-approved POC?
Under the Air Carrier Access Act, U.S. airlines cannot refuse a properly labeled FAA-approved POC on aircraft with 19+ seats, provided you give advance notice and carry sufficient battery. If refused, request to speak with the airline's Complaint Resolution Official.
How much battery do I need for a flight?
The FAA requires battery capacity for at least 150% of your total travel time, including flight, layovers, and a buffer for delays. Spare batteries must be in carry-on baggage with protected terminals.
