Can You Bring a CPAP Machine on an Airplane?

If you depend on a CPAP (Continuous Positive Airway Pressure) machine for sleep apnea or other breathing disorders, traveling, especially flying, can feel overwhelming. The good news is you absolutely can bring your CPAP machine on an airplane. Airlines and airport security recognize CPAP machines as essential medical devices, not as typical carry-on items, so bringing yours onboard is both allowed and protected by regulations.

In this comprehensive guide, you’ll learn about airline and TSA policies, best packing and security tips, advice for in-flight use, common challenges, and answers to frequently asked questions. Let’s make your next flight with a CPAP machine as smooth as possible!


Are CPAP Machines Allowed on Airplanes?

In simple terms: Yes, you are allowed to carry your CPAP machine onto the plane. In fact, it is your right to do so.

Key points to know:
– CPAP machines are considered medical devices.
– Airlines in the United States and many other countries do not count medical devices, such as a CPAP, against your standard carry-on luggage allowance.
– You are permitted to bring your CPAP machine through security, onto the plane, and use it during your flight (with certain restrictions).


Steps for Traveling with a CPAP Machine

1. Before You Fly: Getting Ready

Preparation is key! Follow these steps before your trip:
Contact Your Airline: Confirm their policies about carrying and using CPAP devices.
Notify Ahead: Let the airline know if you plan to use your CPAP machine during the flight. Some carriers may need advance notice, especially if you need power.
Gather Documentation: Carry a copy of your prescription or a doctor’s note. While rarely required, having these can ease any questions during security or boarding.
Check Equipment Compatibility: If you plan to use your CPAP on the plane, check if your device can run on battery power and if it is FAA-approved for in-flight use.
Charge Extra Batteries: Bring sufficient charged batteries if your flight is long or if in-seat power isn’t available. Airlines rarely provide power compatible with CPAP machines.
Evaluate Water Needs: If your machine uses a humidifier, travel with distilled water in your checked luggage or buy it after arriving. TSA liquid rules apply to all water brought through security.

2. Packing Your CPAP Machine

Here’s how to keep your machine safe and accessible:
Use a Dedicated Case: Most CPAP machines come with a protective travel case. Use it!
Keep It Accessible: Pack the CPAP at the top of your carry-on or in a way that’s easy to remove during the security screening.
Label Your Bag: Add a medical equipment tag to the case for easy identification.
Include Accessories: Pack extra masks, filters, hoses, and power adapters.
Store Distilled Water: If you prefer using your CPAP with water, bring a small bottle, but keep within TSA liquid limits (3.4 ounces/100 milliliters) or plan to purchase after security.

3. Going Through Airport Security (TSA Process)

Security checkpoints are simple if you know what to expect:
Declare It: Tell the TSA officer you’re carrying a CPAP machine.
Remove the Machine: Place the CPAP machine (not the case) in a separate bin for X-ray screening—much like a laptop.
Protect It From Germs: Use a clear plastic bag to keep the CPAP clean and avoid contact with trays.
Additional Checks: TSA officers may swab the machine to check for explosive residue. This only takes a moment and won’t harm your equipment.
Batteries: Spare lithium-ion batteries must be in your carry-on, not checked luggage. Each battery should be stored separately.

4. On the Plane: Storing and Using Your CPAP

  • Stow Under the Seat: Unless you’ll use your CPAP in flight, keep it under the seat. Because it’s medical equipment, it’s excluded from your carry-on item limit.
  • Using Your CPAP:
  • Only use it if the airline allows in-flight use and if your device is FAA-approved.
  • Bring extra batteries, as in-seat power is rare and may not match your plug.
  • If powering it in-flight, arrive early, as certain seats have better access to power outlets (and some have none).
  • Use bottled or distilled water for humidifiers. Never use non-distilled water unless absolutely necessary.
  • Avoid Blocking Exits: Ensure your machine and cords do not obstruct aisles or exits at any time.

Potential Challenges and How to Manage Them

While most air travel with a CPAP is straightforward, you might face occasional challenges:

1. Power Access During Flight

  • Not all plane seats have universal power outlets.
  • Solution: Travel with FAA-approved external batteries, fully charged.

2. Limited Space Onboard

  • Airplanes are cramped, especially in economy class.
  • Solution: Use the machine only if necessary, and choose seats near the power supply if possible.

3. Water Restrictions

  • Bringing large amounts of liquid through security is not allowed.
  • Solution: Carry only the minimum needed for flight (3.4 ounces/100 mL) or buy bottled/distilled water after clearing security.

4. Cleanliness During Security

  • Machines are exposed during screening.
  • Solution: Protect your device in a clear plastic bag and consider cleaning it after your flight.

Practical Tips for Easier CPAP Air Travel

  • Download Your Device Manual: Keep it on your phone or in a cloud storage app for quick reference.
  • Check for Travel-Friendly Models: Some manufacturers offer compact versions with battery options.
  • Consider Backup Supplies: Bring spare tubing, filters, and masks in case of damage or loss.
  • Know the Airline’s Power Options: Research your airline and seat type for power details before booking.
  • Prepare for Layovers: If you have long layovers, pack enough batteries and water for extended use.
  • Carry a Universal Adaptor: International travelers may need plug and voltage adapters for hotel use.
  • Sanitize After Travel: Wipe down your CPAP components after flights to keep them germ-free.

Special Advice for International CPAP Travel

  • Check Voltage and Plug Types: CPAPs generally use 110–240V, but plug adapters are often necessary abroad.
  • Review Local Airline Rules: Non-U.S. airlines may have different policies. Check online or call the airline directly.
  • Keep Documentation Handy: Customs officials sometimes ask for proof that medical devices are for personal use.

Summary

Bringing your CPAP machine on an airplane is not only possible but also your right as a traveler who relies on medical devices. With proper preparation, your CPAP won’t slow down your travel—and will help you feel your best wherever your journey takes you.

Remember to check with your airline before flying, pack your equipment thoughtfully, prepare for TSA screening, and double-check power options if you plan to use your device during the flight. With these steps, traveling with a CPAP becomes simple, safe, and stress-free.
