Do you need a prescription to fly with a CPAP?

If you bring the water through airport security, they will open and test it for explosives. You may also want to include a letter from your doctor or a copy of your prescription for the CPAP machine, but in most cases, you won't need to show it.



You do not need a physical prescription to bring or use a CPAP (Continuous Positive Airway Pressure) machine on a flight in 2026, but having one is a "pro" safety measure. Under the Americans with Disabilities Act (ADA) and FAA regulations, a CPAP is considered a medically necessary device. This means it does not count toward your standard carry-on or personal item limit; you can bring it in its own dedicated case for free. While TSA agents will not ask for a prescription during screening, they will require you to remove the machine from its carrying case for X-ray inspection (though you can keep the tubing and mask inside). If you plan to use the machine during the flight, you must ensure it has an "FAA Compliance" sticker on the bottom, and you should check with the airline to see if they require a Medical Data Sheet for battery-operated use. Carrying a digital copy of your prescription is mainly useful for "Customs" in foreign countries or in the rare event your machine breaks and you need to source a replacement part while traveling.
