Most modern CPAPs are tiny—like a tin of cookies. They fit in a backpack. Don’t bring the giant hospital-grade model from 1995. That’s overkill. And it won’t fit under the seat.
Also, consider the smell. CPAP tubing can get a bit funky. Wash it before you fly. Or your neighbor will smell “old cheese and warm plastic.” Not a great first impression.
International Borders: Gateways of Confusion
Flying international? The rules get weird. Some countries require a prescription to even bring it in. Others (looking at you, Japan) want a customs declaration form. Fill it out or risk the CPAP being confiscated.
And for the love of sleep, never lie about what it is. Don’t call it a “medical massager.” Just say “sleep apnea device.” Customs officers have heard it all. They’re not amused by your jokes.
