Do you need a medical certificate to take a Continuous Positive Airway Pressure (CPAP) machine on a plane?

Traveling with a CPAP Machine on a Plane

You do not need a medical certificate to take a CPAP machine on a plane, but having documentation from your healthcare provider is recommended to facilitate the security process and ensure smooth travel. 1

General Requirements for Traveling with CPAP

• CPAP machines are considered medical devices and are allowed as an additional carry-on item that doesn't count toward your luggage allowance 1
• While not legally required, it's advisable to carry a letter or medical certificate from your healthcare provider that:
  • Confirms your diagnosis of obstructive sleep apnea
  • States your need for the CPAP device
  • Includes contact information for your healthcare provider 2

Pre-Travel Planning

• Contact your airline at least 48 hours before departure to inform them you'll be traveling with a CPAP machine 1
• Ensure your CPAP machine is labeled with your name and contact information 2
• Pack your CPAP in your carry-on luggage, never in checked baggage, to prevent loss or damage 1
• Consider bringing:
  • A copy of your prescription or medical letter
  • Device manual
  • Extension cord and appropriate power adapters for your destination
  • Distilled water if you use a humidifier (or plan to purchase at destination) 2, 1

Airport Security Considerations

• CPAP machines must go through X-ray screening separately from other carry-on items 1
• You may request a visual and physical inspection of your CPAP if you're concerned about X-ray damage (though modern machines are generally X-ray safe) 1
• Security problems with CPAP machines are relatively rare, occurring in only about 4% of air travel trips 1

During the Flight

• You are generally not permitted to use your CPAP machine during takeoff and landing 1
• For long flights, usage during the flight is at the discretion of the airline and may require:
  • Advance notification
  • Seating near a power outlet
  • Battery operation if no power outlet is available 3, 1
• Research shows that most CPAP users do not use their machines during overnight flights, even though this could potentially improve in-flight sleep quality 1

Common Pitfalls and How to Avoid Them

• Power supply issues: Research shows approximately one-third of travelers face problems with power cords or adapters 1
  • Solution: Bring universal adapters and check voltage requirements for international travel
• Security delays: Having your machine flagged for additional screening 1
  • Solution: Arrive early and have documentation ready
• Water/humidifier issues: Difficulty obtaining distilled water at destination 1
  • Solution: Research availability at your destination or consider traveling without the humidifier for short trips

Special Considerations

• For international travel, check specific country requirements as they may vary 3
• If you're traveling to high altitudes, your pressure settings may need adjustment - consult your sleep specialist before departure 4
• After substantial weight changes or if experiencing new symptoms, a repeat sleep study might be needed to ensure your current settings are appropriate 4

By following these guidelines, most CPAP users can travel without significant difficulties. Studies show that the vast majority of CPAP users (81%) successfully take their machines when traveling, and usage while away typically doesn't differ from usage at home 1.
