Traveling With a Portable Oxygen Concentrator

A portable oxygen concentrator (POC) gives oxygen-dependent patients the freedom to fly, travel, and stay active. This guide covers your federal rights, the universal rules that apply to every U.S. airline, and the current policies for all major carriers — so you can board with confidence.

All units we carry meet FAA acceptance criteria for in-flight use. Questions about which unit is right for your travel needs? Call us at 1-866-218-0902.

⚖️ Your Federal Rights as a POC Traveler

The Air Carrier Access Act (14 CFR Part 382) protects your right to fly with your own portable oxygen concentrator on any U.S. commercial flight. Key protections:

• All U.S. airlines must permit FAA-approved POCs in the cabin — they cannot refuse you.
• Your POC is classified as an assistive medical device and does not count toward your carry-on or personal item allowance.
• Airlines cannot require you to rent equipment from any specific vendor.
• You may bring extra batteries and accessories at no additional charge.
• If an airline challenges your POC at the gate, ask to speak with their Complaint Resolution Official (CRO) — every U.S. airline is required to have one on duty.

📋 Rules That Apply to Every Airline

• FAA-approved POC only. Your concentrator must display the FAA acceptance label or appear on the FAA-approved device list. If the label on your battery is worn or faded, get it documented before you travel — gate agents are inspecting battery labels more closely since 2025.
• No compressed or liquid oxygen. No U.S. airline accepts oxygen tanks, cylinders, or liquid oxygen systems in the cabin or as checked baggage.
• Battery rule — 150% of total travel time. Most airlines require battery capacity equal to 150% of your total scheduled flight time, including layovers and connection time. Example: a 6-hour total travel day requires 9 hours of battery capacity on board. United Airlines requires flight time + 3 hours.
• Notify the airline in advance. Most airlines require 48 hours' notice for domestic travel; 72 hours for international. Notify when booking and confirm with the airline before departure.
• Notify the gate agent on arrival. Upon reaching the airport, tell the ticket counter and gate agent you are traveling with a POC.
• TSA inspection. TSA allows hand-inspection of your POC so it does not need to go through the X-ray machine. Inform the TSA officer at security.

Allegiant serves dozens of Florida airports — Sarasota (SRQ), Fort Myers (RSW), St. Pete–Clearwater, Orlando Sanford, Punta Gorda, and more — making it a top choice for Southwest Florida oxygen users traveling to see family or for vacation.

• Notify at least 48 hours before departure. Add your POC to your reservation via Allegiant's Manage Travel tab online, or call 1-702-505-8888 during customer service hours.
• Notify the gate agent on arrival at the ticket counter or gate that you are traveling with a POC.
• FAA-approved label or list. The Allegiant agent will inspect your device — it must display the FAA-approved label or appear on the FAA-approved device list. Approved models include the Inogen One G5, Philips Respironics SimplyGo, CAIRE Freestyle Comfort, and Oxlife Independence, among others.
• Battery: flight duration + 50% (equivalent to 150% of scheduled flight time).
• Physician consent form required on physician's official letterhead — available from Allegiant when you notify them of your POC use.
• No compressed or liquid oxygen permitted.
• POC may be stowed under the seat in front of you, in the overhead bin, or gate-checked if it does not fit in the cabin.
• Free seat assignment available for passengers with disabilities — request at least 24 hours in advance.
• CPAP machines and ventilators are also accepted as carry-on or checked baggage.

🌐 Current Airline POC Policies

Policies change — always confirm with your airline before travel. Links go directly to each carrier's accessibility or special needs page.

Policies are subject to change without notice. Always verify current requirements directly with your airline before travel. If you are flying on a codeshare or partner flight, contact the operating carrier — not the ticketing carrier — for their POC policy.
