Yes, a CPAP machine can go in your carry‑on; it’s classified as a medical device allowed on board and doesn’t count toward your carry‑on limit.
CPAP machines are allowed in airplane cabins and the Department of Transportation (DOT) protects your right to fly with a CPAP and even use it during flight. Airlines treat CPAPs as assistive medical equipment, so your device does not count against your carry-on baggage allowance on U.S. airlines. You can bring your usual carry-on bag and personal item, plus your CPAP in its own case, without extra fees or fuss.
It’s best to pack the CPAP in its own dedicated carry case – ideally the one it came with. Keeping it separate protects the device and signals it’s medical gear – meaning it won’t count against your luggage allowance.
CPAP Travel Rules at a Glance
Let’s break down the key questions travelers have about flying with a CPAP machine. The table below summarizes what to expect:
| Question | Carry‑On Policy | Details |
|---|---|---|
| Allowed on board? | Yes | Treated as a medical device; airlines must allow it in the cabin. |
| Counts toward bag limit? | No (U.S. flights) | Does not count as one of your carry‑on items. Pack it in a separate medical bag for the free allowance. |
| TSA security screening needed? | Yes | Remove your CPAP machine from its case for X‑ray screening. Mask and tubing can stay in the bag. |
| Use during flight? | Yes, if needed | FAA‑approved CPAPs can be used on board. Inform the airline if you plan to use it and bring battery power, since in‑seat power isn’t guaranteed. |
| Should you check it instead? | Not recommended | Allowed in checked bags, but there’s risk of damage or lost luggage – carry it on to be safe. |
Not only is carrying your CPAP permitted, it’s strongly recommended. If you check it and your luggage gets lost or damaged, you could be left without your CPAP.
Getting Through TSA Security Smoothly
Airport security is often the part that worries CPAP users the most. The thought of a TSA agent inspecting your machine can be nerve‑wracking, but don’t worry – TSA sees CPAPs all the time and has clear procedures to keep things simple.
When you reach the security checkpoint, be prepared to take your CPAP machine out of its case. Like a laptop, the device itself needs to go through the X‑ray scanner on its own. You can keep the hoses, mask, and other accessories in the carry case; usually only the main unit (the pump) must be screened separately. A pro tip is to place your CPAP machine in a clear plastic bag before putting it in the bin. This way, the device doesn’t directly touch the conveyor belt or bin surface, keeping it more sanitary. TSA agents have no issue with this – in fact, they often suggest it.
Once on the X‑ray belt, your CPAP might also undergo an explosive trace swab test. Don’t be alarmed if an officer opens the machine’s compartment or swipes it with a special cloth; they’re just checking for any trace of banned substances. This is standard for many electronic devices and ensures safety. The process only takes an extra minute or two. Most TSA officers are familiar with CPAP machines and handle them carefully and respectfully. If you’re worried, you can always say “It’s a CPAP medical device” as you place it out for screening – agents typically appreciate the heads‑up.
Packing Your CPAP for Travel
When packing your CPAP, empty the humidifier chamber to prevent leaks and give the device a quick clean (mask and tubing included). Pack the machine in its padded travel case (or wrap it in a soft cloth) so it’s cushioned from bumps during travel. It’s a good idea to keep all the CPAP parts together so nothing gets left behind.
In‑Flight Use: Sleeping With Your CPAP on the Plane
If you have a long overnight flight, you might wonder if you can actually use your CPAP in the air. Good news – using a CPAP during flight is generally allowed on U.S. airlines, as long as your device meets certain criteria. First, check that your CPAP machine is labeled as approved for in‑flight use by the Federal Aviation Administration (FAA) (look for a sticker on the unit). Most modern CPAP models are already airline‑approved. If you plan to use it during flight, notify your airline in advance and carry ample battery power, since in‑seat power isn’t guaranteed.
Most airlines allow CPAP use on board, but airplane cabins don’t always have accessible power outlets. Bring your own CPAP battery if you intend to sleep with the machine. FAA regulations require lithium‑ion CPAP batteries to be packed in carry‑on (not checked) luggage for safety. Many airlines require that you have battery power for at least 150% of the flight duration – a common requirement to ensure you have enough battery even for delays. To conserve power (and avoid spills), it’s wise to turn off the humidifier or remove its water chamber during the flight.
Before using your CPAP on the plane, let the flight attendants know. They may want to see the FAA approval label on your device or any paperwork you have from the manufacturer stating it’s cleared for in‑flight use. Once everything is verified, you’re good to go. Using a CPAP at 30,000 feet might feel a bit odd at first, but it can make a world of difference on a long flight if you need it.
Extra Tips for Hassle‑Free CPAP Travel
| Travel Tip | Do This | Why It Helps |
|---|---|---|
| Use a dedicated CPAP bag | Pack the machine in its own carry case (add a medical tag if possible). | Avoids counting as regular luggage and protects the device. |
| Carry backup accessories | Bring spare mask cushions, filters, or even a backup mask. | Handy if something breaks or gets lost far from home. |
| Mind the power supply | Take an extension cord and the right plug adapters. | Outlets might be far from the bed or a different type abroad. |
A few last reminders: if you’re traveling internationally, check the local power outlets and voltage. Most CPAP machines are dual‑voltage, but you’ll need the appropriate plug adapter to use it overseas. Some countries’ airport security might not see CPAPs as often. Having a doctor’s note explaining the device (or a TSA medical notification card) can be useful if language barriers or unfamiliarity arise. In most cases, though, you’ll sail through airports worldwide with your CPAP just fine.
Above all, remember why you have that CPAP in the first place – to help you breathe and sleep better. Don’t let a trip tempt you into leaving it behind. Each night of good sleep makes your travels safer, healthier, and more enjoyable. With the strategies outlined here, you can confidently carry your CPAP machine in your carry‑on and rest easy knowing both you and your trusty device will arrive ready for a good night’s sleep.
