So, can you use a CPAP on an airplane? Absolutely. But it’s not a “grab-and-go” situation. You need the right battery, a doctor’s note, and a bit of courage. I’ve done it five times now, and each trip, I wake up refreshed instead of groggy and grumpy. (Which is more than I can say for the guy who drank three mini-bottles of wine before takeoff.)
If you’re nervous, start with a short flight—like an hour or two—to get the hang of it. And remember: you’re not being high-maintenance; you’re taking care of your health. The flight attendants deal with worse stuff every day, trust me. So pack your CPAP, call the airline, and get that good sleep at 35,000 feet. You deserve it. And if anyone gives you a hard time, just tell them the FAA said it’s okay. That usually shuts them up.
