Therapy that only works in your own bedroom is therapy with a hole in it. Share what you have learned about taking it with you. Ground worth covering in this thread: Flying — CPAP machines are medical equipment and generally travel as an extra item rather than as carry-on allowance, but the rules are set by the airline and the airport, not by us. Check your specific airline before you fly, and keep the machine in the cabin rather than in the hold. Power away from mains — batteries, car adapters, what your machine draws with and without the humidifier (the humidifier is usually the expensive part), and what you switched off to make a night last. Altitude — many machines compensate automatically; some need telling. Worth knowing which yours does before a mountain holiday. Water — what you use for the humidifier when you are away from your usual supply, and how you dry the chamber in a hotel room. Camping, cabins and boats — the setups that actually survived. Sleeping in other people's houses — the noise question, the socket question, and the "do I explain it?" question. Practical reports, please: what you took, what happened, what you would change. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Security and luggage. In most countries a therapy device travels as a medical device and does not count against your hand-luggage allowance, and it should travel in the cabin — not in the hold, where it can be crushed or frozen. Expect it to be taken out of the bag and screened separately, sometimes swabbed. A printed line from your supplier or a copy of the prescription is not usually required and is worth carrying anyway, because it converts a five-minute conversation into a ten-second one. Rules vary by country and change — check your airline and your destination rather than a forum post from last year. Water. Empty the humidifier chamber before you fly; carry it dry. Distilled water is hard to find in some countries — bottled still water is what most people fall back on, and a few dry nights are not a catastrophe. Do not fill the chamber from a tap you would not drink from. Hotels. Ask for a room with a socket near the bed; it is a normal request and nobody thinks anything of it. Take a short extension lead if you want to stop thinking about it entirely. Add what you have learned — especially about countries with unusual rules. This thread is more useful the more of you edit it by replying to it.
