Yes, you can check a CPAP machine in your luggage, but most experts recommend carrying it on board to avoid loss or damage.
You’ve zipped your CPAP into its travel case and packed your toiletries. The question hovers: should the device ride in the cargo hold or stay beside you in the cabin?
The short answer is that the TSA allows CPAP in luggage — both checked and carry-on. Yet the safer choice, according to sleep specialists, is to keep it at your side.
TSA Rules for CPAP in Luggage
The official position is straightforward. The Transportation Security Administration permits CPAP, BiPAP, and APAP devices in checked baggage and carry-on bags. The device can stay inside its carrying case for X-ray screening, though you may need to remove it from the case.
If you pack the CPAP bag inside another suitcase, you will likely have to remove it at the checkpoint unless you have TSA PreCheck. This adds a step but doesn’t stop you from checking it.
One twist: TSA officials have told the American Association of Sleep Technologists that putting your CPAP in checked luggage reduces the chance it gets left behind at the checkpoint. That advice clashes with most expert recommendations.
Why Most Experts Say Carry It On
The logic behind the carry-on preference is simple: a CPAP machine is a medically necessary device. If checked luggage gets lost or damaged, you lose more than clothes — you lose therapy. Airlines generally do not count the CPAP toward your carry-on allowance because it qualifies as a medical device.
- Loss or delay: Checked bags get rerouted. A CPAP in the hold might not arrive with you.
- Damage risk: Baggage handlers toss suitcases. A hard-sided case helps, but drops can crack the device’s screen or humidifier chamber.
- Humidifier water: If you leave water in the tank, it can leak and damage electronics. Manuals advise emptying the chamber before travel.
- Battery restrictions: If your CPAP uses a lithium battery, the device must comply with FAA battery rules — carry-on is standard for large lithium batteries.
- Accessibility: On a long flight, you can use the device if you need it, especially on overnight trips.
These factors push the scale toward carry-on. The Sleep Foundation and Resmed both recommend keeping the device with you for these reasons.
Packing Your CPAP for Checked Luggage
If you decide to check your CPAP despite the risks, you can still protect it. The key is padding and positioning. Place the machine in a hard-sided suitcase and wrap it with clothes on all sides.
The humidifier chamber can travel in your checked bag as well — but only if it’s completely dry. Any residual moisture condenses in the cargo hold’s lower pressure and temperature, which could cause leaks onto the electronics.
Resmed’s travel tip sheet suggests packing the CPAP in a carry-on bag and notes that the TSA allows CPAP in luggage for both checked and carry-on.
| Option | Pros | Cons |
|---|---|---|
| Carry-on (free medical device) | Device stays with you; no loss/damage risk; can use during flight | Must remove at TSA scanner; takes overhead bin space |
| Checked luggage (hard-sided suitcase) | One less item to carry; TSA official sometimes recommends it | Risk of loss, theft, or damage; humidifier water must be emptied |
| Checked luggage (soft-sided case) | Easy to pack | Minimal protection; crush risk |
| Device in original carrying case inside suitcase | Adds some padding; case may fit inside bag | Must remove case at TSA if packed inside; case may not fit small suitcases |
| Ship CPAP ahead to destination | No airport hassle; guaranteed arrival before you | Costly; requires planning; device unavailable before departure |
Whichever method you choose, label your CPAP bag with your contact info inside and out. A business card taped to the device itself can help if it gets separated.
Steps for Traveling With Your CPAP
A few specific actions before and during your trip can save headaches. Follow this sequence for a smooth experience.
- Call your airline before booking: Confirm their medical device policy. Most US carriers allow CPAP as a free carry-on, but international airlines may have different rules.
- Empty the humidifier chamber: Remove all water and dry the tank with a soft cloth. Leave the chamber open for a few hours to air out before packing.
- Pack a travel-sized extension cord: Some planes have power outlets near seats, but the cord may not reach. A 3- to 6-foot cord helps.
- Carry a copy of your prescription: Rarely requested, but useful if security or airline staff question the device.
- Arrive early: Removing the CPAP at TSA screening takes extra time. Give yourself an extra 10 minutes.
If you use a BiPAP or APAP, the same rules apply. All variants fall under the TSA’s medical device category.
What If You Must Check Your CPAP
Sometimes carry-on space runs out or you’re connecting through a tight gate. If you must check the device, take these precautions. Use a hard-sided suitcase with thick clothing padding around the machine. Place the CPAP in the middle of the bag, not near the wheels or handle.
The Sleep Foundation advises against checking CPAP equipment in soft-sided luggage. If you must check it, their Sleep Foundation carry-on recommendation notes that a hard case provides the best protection. Remove any removable parts — like the water chamber or tubing — and pack them separately inside the same suitcase, wrapped in socks or towels.
Consider using a secondary travel CPAP if you have one. Some users keep an older machine as a travel backup, leaving their primary device at home safe.
| Packing Checklist | Checked Bag | Carry-on |
|---|---|---|
| Empty humidifier chamber | Yes | Yes |
| Hard-sided suitcase | Recommended | N/A |
| Extension cord | Optional | Yes |
| Prescription copy | Yes (in carry-on) | Yes |
| Lithium battery backup | Not allowed in checked | Yes (under 100 Wh) |
The Bottom Line
Checking a CPAP in luggage is allowed by the TSA, but comes with risks of loss, damage, or delay. Carrying it on board — free of charge as a medical device — is the safer route. Use a hard case if you must check it, and always empty the humidifier.
For specific questions about your airline’s policy on CPAP carry-on or checked luggage, contact your airline directly before your flight and confirm their medical device allowances for your exact travel dates and route.
