CPAP Machines and Flying
How to Travel With Ease and Confidence
Travelling with a CPAP machine may seem daunting at first, but it doesn’t have to be. Whether you’re flying for business or taking a well-earned holiday, rest assured: with the right machine, smart packing, and a few helpful accessories, staying on top of your sleep apnea therapy while flying is not only possible—it’s simple.
At Sove CPAP Clinic’, we’re committed to helping you continue your therapy wherever life takes you. This guide will show you what to know, what to pack, and what to expect when bringing your CPAP on board.
Airlines treat CPAP machines as essential medical devices
The good news? Most airlines around the world recognise CPAP machines as essential medical equipment. That means they do not count toward your carry-on baggage allowance, and you are allowed to bring them into the cabin and keep them with you at all times.
Airlines will generally let you use your CPAP on board during flight, particularly on long-haul or overnight journeys.
Still, it’s always smart to notify your airline in advance. Let them know you’ll be flying with a CPAP machine and ask about their policies. Some airlines may ask for a doctor’s letter or a medical equipment clearance form, especially if you plan to use it in flight. You may also be asked to sit in a seat near a power outlet if available.
Additionally, having the correct documentation, such as a medical certificate or CPAP compliance report, can help avoid delays or confusion at boarding. Keep a printed and digital copy on hand.
Travel-friendly CPAP models make flying easier
Not all CPAP machines are created with travel in mind. For frequent flyers or those who want to pack light, travel CPAPs are compact, lightweight, and designed to go wherever you go. They often weigh less than 500 grams and fit easily into carry-on luggage.
Here are a few features that make travel CPAPs ideal for flying:
- Compact size: Many travel models are palm-sized and come with a sleek travel case.
- FAA-approved: Most travel CPAPs (like the ResMed AirMini’) are FAA-compliant, meaning they’re cleared for in-flight use.
- Waterless humidification: Instead of a traditional water-based humidifier, these machines may use a cartridge system that captures and returns moisture from your breath—perfect for avoiding the hassle of travelling with distilled water.
- Battery compatibility: If your seat doesn’t have power, many travel machines can run off external battery packs approved for air travel.
- App connectivity: Many devices come with Bluetooth-enabled apps that allow you to track your sleep data while you’re away.
Some standard-size machines can also be used in-flight, but they’re bulkier and require more power support. If you’re not sure which machine is best for travel, our team at Sove CPAP Clinic can help you compare and even trial travel models before your trip.
When considering a travel model, think about your trip duration, cabin conditions, and what comforts you value most. If you’re a light sleeper, for example, a machine with ultra-quiet operation may be essential.
Accessories can solve power, hygiene and comfort issues
When flying with your CPAP, a few well-chosen accessories can make all the difference in maintaining therapy and comfort while away from home.
Power supply and backup:
Travel batteries: Many brands offer lithium-ion battery packs that last a full night or more. Always check that your battery is airline-compliant (typically under 160Wh) and bring your machine’s power adapter too.
Power cords and adapters: If flying internationally, don’t forget the appropriate travel adapter for your destination. Some adapters have surge protection which is helpful in areas with unstable voltage.
Inverter cables: For road travel or layovers, having a DC adapter or inverter can allow CPAP use in vehicles or other non-standard outlets.
Humidification support:
Waterless humidifiers: As mentioned, systems like ResMed’s HumidX allow for comfortable humidification without a bulky water chamber.
Mask wipes and liners: Easy to pack and useful for keeping your mask clean between flights. Liners also improve comfort and reduce the chance of skin irritation or leaks due to pressure changes during ascent or descent.
Portable cleaning systems: Small UV or ozone-based cleaners can help you sanitise your mask and tubing while travelling, particularly on longer trips.
General tips:
- Keep your machine in a hard-shell travel case to prevent damage.
- Label your CPAP bag clearly with a medical equipment tag for easier identification at checkpoints.
- Carry a copy of your prescription or a note from your doctor, just in case security or airline staff have questions.
- Consider insurance: Travel insurance that covers medical equipment loss or damage can offer peace of mind.
We also recommend doing a test run the night before your trip using only your travel setup. This gives you peace of mind that everything is functioning smoothly before you’re airborne.
ALWAYS FOLLOW THE DIRECTIONS FOR USE. CPAP is used for Obstructive Sleep Apnoea treatment. When considering whether CPAP is right for you, speak to your doctor.
Frequently Asked Questions
Does a CPAP machine count as a carry-on when flying?
No, it doesn’t. Airlines typically treat CPAP machines as essential medical equipment, which means they are excluded from your carry-on baggage limit. You can bring your CPAP machine in addition to your standard carry-on and personal item. Just make sure it’s clearly labelled and ideally in a travel case for easy handling.
It’s helpful to store any accessories (like masks or tubing) in the same case to avoid misplacement. If you’re travelling with multiple bags, always keep the CPAP with you, not in checked luggage.
What are the rules for flying with a CPAP machine?
Each airline has its own policy, but here are general rules that apply:
- You can carry your CPAP machine on board as medical equipment.
- Most travel machines are FAA-approved and safe for in-flight use.
- Notify your airline 48–72 hours before travel if you plan to use the device on board.
- A doctor’s letter may be requested, especially for international flights.
Do airlines charge for CPAP machines?
No, airlines do not charge for bringing a CPAP machine. It’s treated like a wheelchair or crutches—as a medical necessity, not a personal item. That said, you are responsible for bringing your own power source (battery) if no plug is available onboard, and for any damage that may occur without a protective case.
Some budget airlines may be unfamiliar with CPAP policies, so be proactive and carry documentation to clarify its medical status.
How should I pack a CPAP machine for air travel?
Use a dedicated travel case or padded carry bag. Most machines come with one. Inside, pack:
- The machine and tubing
- Your mask and headgear
- Power supply and battery (if needed)
- Backup filters and wipes
- Prescription or medical letter
Use cable organisers to keep cords tidy. Wrap delicate parts in soft cloths if your case doesn’t have compartments. Always keep the machine dry and clean. Avoid placing anything heavy on top of it.
Can a CPAP machine go through airport security checks?
Yes. CPAP machines go through airport security scanners just like laptops. You’ll be asked to remove the machine from its case, but not the tubing or mask. Placing it in a bin is standard procedure.
Some security officers may wipe the machine for trace explosives. This is harmless to the device. To minimise contact, place your machine in a clear plastic bag inside the case. If you have concerns, inform the officer it is medical equipment.
In some countries, additional screening may occur. Having your documents handy can speed up the process.
Do airplanes have outlets for CPAP machines?
Some do, but not all. On long-haul international flights or business class cabins, you’re more likely to find in-seat power outlets. Still, these vary in voltage and wattage, and not all support CPAP power needs.
That’s why many travellers bring a portable CPAP battery as a backup. Make sure it’s airline-compliant (typically <160Wh) and check if your airline allows in-flight charging. Always board with a fully charged battery just in case.
It’s also a good idea to know how long your machine can run on battery power. Some advanced models offer sleep tracking through the night, even without internet access, which can be helpful for monitoring.
Is It Worth Getting a Travel CPAP Machine?
For many CPAP users — especially frequent flyers or those with an active lifestyle — a travel-specific CPAP machine is absolutely worth it. Here’s why:
Portability: Travel CPAPs are smaller and lighter, fitting easily into carry-ons or backpacks. This makes them easier to carry through airports, onto planes, or into hotels.
Battery compatibility: Most travel models have approved battery options for overnight use, which is ideal for camping, red-eye flights, or remote locations.
Waterless humidification: Options like HumidX (ResMed) or heat-moisture exchange systems remove the need to carry distilled water.
Protection for your primary machine: Using a travel machine while away protects your full-size home device from bumps or wear.
Simplicity: Travel units often have fewer parts and a more compact layout, making them faster to pack and easier to maintain.
