76% of people with sleep apnea use their CPAP machine at least some of the time while traveling. Another 10% don't use it on trips and 10% don't travel.

People with Obstructive Sleep Apnea (OSA) in 2026 typically travel with a portable CPAP (Continuous Positive Airway Pressure) machine. Because CPAP machines are classified as essential medical devices, they do not count toward a passenger's carry-on luggage limit under FAA and international aviation rules. On long-haul flights, passengers often use their machines at their seats to ensure they can sleep safely without experiencing apneas. Modern travel CPAPs are compact, whisper-quiet, and often battery-powered, which is crucial since in-seat power outlets on planes are not always guaranteed to support medical equipment. Travelers are advised to bring a doctor’s note and a copy of their prescription to avoid delays at security checkpoints, although TSA agents in 2026 are highly accustomed to seeing these devices. It is also recommended to use distilled water for the humidifier if the airline allows it, though many travelers opt to run their machines "dry" (without the humidifier) during the flight to prevent spills and simplify the setup in a cramped cabin environment.
