Flying with Medical Equipment
CPAP, oxygen concentrators, and medication rules — what's allowed on board and how to prepare.
CPAP machines and other approved devices
CPAP machines are generally allowed as an extra item beyond your regular carry-on allowance and don't count toward your bag limit. Bring a letter from your doctor, and check your airline's policy if the device is battery-powered.
Oxygen concentrators
Portable oxygen concentrators are permitted on most airlines but usually need to be an approved model, plus advance notice — often 48–72 hours — along with a doctor's certification of medical need.
Carrying medication and supplies
Keep medication in its original, labeled packaging in your carry-on rather than checked luggage. Liquid medications and related supplies, like insulin, are generally exempt from standard liquid limits, but declare them at security and carry a doctor's note for syringes or unusual equipment.
Planning ahead with the airline
Most airlines have a dedicated medical or special-assistance desk — call them directly rather than the general line, especially if you're traveling with oxygen, powered equipment, or need extra boarding time.
This is general travel guidance, not medical advice. Always confirm equipment and medication policies with your airline and doctor before you fly.
