Yes you can take your PAP on the airplane. A PAP machine should be taken as a carry on only and not checked as luggage. Please ask us for a copy of your prescription prior to travel so you can have this documentation for the airline if required.
Contact the airline prior to your trip to confirm their PAP policy. Also inquire if you will have access to a power supply. Not all airlines will have means for you to use your PAP machine on the plane. You may have to bring a PAP battery if you plan to use the device in flight. Our PAP batteries meet all requirements to be taken on a plane. You most likely will not be able to use your humidifier on the plane as the plane or battery will not likely provide enough wattage to run the humidifier. Also pack an extension cord as you may be a distance from the nearest electrical outlet. Be prepared to take your machine out of the bag so it can be X-rayed.
