FAA-approved portable oxygen concentrators for air travel

FAA-Approved POCs: Fast Facts

  • Legal Basis: 14 CFR Part 121.574 and Advisory Circular 120-95A (effective May 2016)
  • Your Right: Air Carrier Access Act (ACAA) requires airlines to allow FAA-approved POCs on flights with 19+ seats
  • 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
  • All Phases of Flight: FAA-approved POCs may be used during takeoff, flight, and landing
  • 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."
Every POC Sold by Main Clinic Supply Is FAA-Approved All 11 portable oxygen concentrator models in our lineup meet FAA acceptance criteria. You can verify this on any unit by locating the red-text compliance label on the device exterior.

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.
Compressed Oxygen Tanks Are NOT Permitted Compressed and liquid oxygen cylinders are prohibited on commercial aircraft. Only portable oxygen concentrators (which concentrate oxygen from ambient air) are permitted. If you currently use oxygen tanks, you will need a POC for air travel.

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.

Battery Calculator Example
  • 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
The Inogen Rove 6 with one extended (16-cell) battery provides up to 13 hours at setting 1 or up to 10 hours at setting 2. For settings 3 and above, carrying a spare battery is essential.

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.
