Yet, more than three-quarters of CPAP users say they use their CPAP machine at least some of the time while traveling. “It's important to pack your CPAP machine whenever you travel, since OSA must be treated continuously, just like any other medical condition.”

Passengers with sleep apnea on long-haul flights in 2026 typically bring their CPAP (Continuous Positive Airway Pressure) machine as part of their carry-on luggage. Because CPAP machines are classified as essential medical devices, they do not count toward your standard carry-on bag limit on most major airlines. To use the device in-flight, you should contact the airline at least 48 hours in advance to confirm their specific "Electronic Medical Device" policy; some airlines require a doctor's letter or a serial number for the machine. For power, you must ensure your seat has a functional universal power outlet or bring an FAA-approved lithium battery pack, as most aircraft outlets cannot support the high "startup" wattage of older CPAP models. Many frequent travelers now opt for "travel-sized" units like the ResMed AirMini, which are significantly lighter and designed for portable use. It is also vital to empty the humidifier chamber before flying to prevent spills and to carry a printed copy of your prescription in case you are questioned by security or customs officials during your journey.
