Traveling with sleep apnea therapy equipment might seem daunting at first, but flying with a CPAP machine is easier than you think. With a little preparation (and a few smart accessories), your air travel experience can be seamless, whether you’re crossing the country or heading off on an international adventure.
Here’s everything you need to know about getting your CPAP device through airport security, onto the plane, and even using it during your flight, including some helpful affiliate links to gear we personally travel with.
CPAP Machines and Airport Security: What You Need to Know
Important Security Tips:
- CPAP machines are considered medical devices.
- TSA allows you to bring a CPAP as a third item (beyond carry-on and personal item).
- You must take it out for x-ray screening at the security checkpoint (they say this but I’ve never been asked to do so).
- Use a clear plastic bag to protect your equipment.
- TSA agents may swab the device to check for explosives.
CPAP Machines Are Medical Devices
First things first: your CPAP unit is classified as medical equipment under TSA and airline policies. That means it doesn’t count against your regular carry-on allowance. You can bring a carry-on bag, a personal item, and your CPAP carrying case without issue.
Getting Through the TSA Screening Process
Technically they say that at security, you’ll need to take your CPAP machine out of its travel case and place it in a clear plastic bag for separate x-ray screening. Accessories like your CPAP mask, power cord, and tubing can usually stay in the bag. However, in many years of flying, we’ve never actually been asked to do this. My advice would be to not remove your device unless asked to do so.
Helpful tip: TSA agents may swab the machine for trace explosives, totally normal, and it takes less than a minute. Again this has never happened to us, but technically it could.
Using Your CPAP Machine In-Flight: What the Rules Say
Key Topics for In-Flight Use:
- Most airlines allow CPAPs for in-flight usage.
- Policies vary: very few allow direct plugging into power outlets, most require a battery backup for use in flight.
- Some airlines require medical clearance or 48-hour advance notice.
Different Airline Policies for CPAP Use
Here’s what each airline officially says about traveling with and using a CPAP machine onboard:
- American Airlines: CPAP machines are allowed as assistive devices and don’t count toward your carry-on limit. American recommends bringing fully charged batteries sufficient for 150% of your flight time, as onboard power is not guaranteed.
- Delta Air Lines: You must bring your own battery power for medical devices, with enough charge for 150% of your flight time. While some aircraft have seat outlets, they aren’t designed to support medical devices like CPAPs.
- United Airlines: CPAP machines are permitted and must be FAA approved. You need to bring enough battery power for the full flight plus extra time. United cannot guarantee in-seat power availability.
- Southwest Airlines: CPAP machines are considered assistive devices and can be carried on separately from regular baggage. Southwest recommends keeping all necessary medical equipment in your carry-on, and seat power is not guaranteed.
- JetBlue Airways: You can carry and use CPAP machines onboard, but seat power is not available for CPAP use. Devices must meet FAA guidelines and be stowed properly.
- Alaska Airlines: CPAP machines are allowed as mobility/medical assistive devices and do not count toward the carry-on bag limit. Battery backup is strongly encouraged since seat power is not guaranteed.
- British Airways: CPAP machines are permitted, but you must submit a medical clearance form at least 7 days before travel if you intend to use medical equipment onboard. Battery power sufficient for the flight is required.
- Air Canada: CPAP machines are permitted. Battery-powered medical devices must have individually protected batteries, and advance approval from Air Canada Accessibility Services is required for onboard use.

Always check directly with your airline before your flight, and if you’re traveling internationally, double-check again, because policies can vary based on the destination country.
Pro Tip: Keep printed proof that your CPAP is FAA-approved, plus a copy of your prescription, especially for international flights.
Personal Experience Using a CPAP in Flight
I didn’t know for years that you are not supposed to use in-seat power for a CPAP. My husband has flown dozens of overnight flights and no flight attendant ever said anything…until a Virgin Atlantic flight from Seattle to London when a flight attendant unplugged his machine mid-flight, mid-sleep!
We then learned that stand-alone batteries are required on most airlines, though enforcement seems to be quite varied. We had flown that same Virgin Atlantic route multiple times before and no one had ever said anything.
As it was quite disruptive to his ability to sleep and he was heading in to several days of meetings, we learned the importance of packing a battery so we avoid similar issues in the future.
What to Bring When Flying With Your CPAP Machine
Must-Have CPAP Travel Essentials:
- Battery pack for backup power
- Power cord or plug adapter
- Small extension cord
- Copy of your prescription
- Travel-size cleaning wipes
- Bottled water for humidification
- CPAP travel bag or carrying case
- Backup supplies (mask, hose)
Battery Pack for Backup Power
Even if you’re on a short trip, having a reliable battery pack is crucial for in-flight use. We use and love this one. It’s compatible with most modern CPAP machines and works great for camping, cruise ships, and international travel too.
Power Cord and Plug Adapter
While newer modern CPAPs often work with dual voltage (perfect for international travel), you might still need a plug adapter or DC converter depending on your destination country.
Bringing a small extension cord is also a good idea. Hotels and cruise cabins don’t always have conveniently placed outlets.
Copy of Your Prescription
Always carry a copy of your CPAP prescription. If your machine is lost, stolen, or malfunctions, having the prescription on hand can help you get a replacement quickly at your destination.
Travel-Size Cleaning Wipes
Instead of lugging a big cleaning machine or worrying about finding distilled water, bring travel-size CPAP cleaning wipes. They’re a game-changer for quick cleaning on the go.
Pro Tip: Never use hotel tap water for your CPAP! Always use bottled water or skip humidification if you can’t find distilled. My husband once used unfiltered tap water in Mexico out of desperation and was SO sick for several days…it was as if he had drunk the water directly.
AirMini Travel Bag and Portable CPAP Options
If you’re still using a full-size CPAP, it might be worth investing in a portable CPAP machine like the ResMed AirMini. It’s designed for travel, super compact, and works with waterless humidification cartridges, perfect for short trips and high altitude flights.
The matching AirMini travel bag keeps everything organized and lightweight.
Backup Supplies
Just like you pack extra socks, bring backup CPAP supplies like an extra hose or mask cushion. They take up almost no space in your luggage but can save your trip if something breaks.
With the right prep, flying with a CPAP machine is really no big deal. Treat it like the assistive device it is, stay polite but firm at security checkpoints, and bring your necessary supplies for the plane.
Knowing your airline policies, carrying a backup battery, and investing in a good travel case makes all the difference for a smooth travel experience, and a great night’s sleep, wherever you land.
Sweet dreams at 35,000 feet!
