Yes, you can pack your CPAP in checked luggage, but carry-on is safer
Your CPAP machine can go in checked baggage, but the Transportation Security Administration (TSA) does not recommend it. Checked bags are pressurized and temperature-controlled during flight, so your machine will not be damaged by altitude or cold. The real risk is baggage handlers dropping or crushing your equipment — CPAP machines are delicate, and a $500 to $3,000 device is not worth the gamble when you can keep it with you.
Carry-on luggage is the better choice. Your CPAP fits in a standard overhead bin, you control how it is handled, and you can use it when ready after landing if you need to rest. If you must check it, pack it in a hard-sided case with padding on all sides, and consider purchasing additional baggage insurance through your airline.
Key Takeaways
- The TSA allows CPAP machines in both carry-on and checked baggage, but carry-on protects your equipment from damage during handling.
- Pack your CPAP in its original case or a hard-sided protective case with cushioning if you check it, and never wrap it in plastic that traps moisture.
- Bring your CPAP power cord and any adapters you need in your carry-on bag, since checked luggage delays can leave you without power access.
- Airlines do not count CPAP machines toward your carry-on bag limit on most carriers, so you can bring it as a medical device in addition to your regular luggage.
- If your CPAP uses a humidifier, empty the water tank completely before packing and let it air-dry to prevent mold and leaks during transit.
TSA rules for CPAP machines at security
The TSA treats CPAP machines as medical devices and does not require you to remove them from your bag at security screening. You can leave your machine in your carry-on as you move through the checkpoint. If you prefer, you can remove it and place it in a separate bin so the screener can inspect it without opening your bag.
If you are traveling internationally, check the rules for your destination country before you leave. Most countries allow CPAP machines for personal use, but some require a doctor's letter or proof of prescription. The European Union, Canada, and Australia all permit CPAP travel without special documentation, but rules vary for other regions.
How to pack your CPAP for carry-on travel
Use your CPAP's original carrying case if you have it — these are designed to fit in overhead bins and protect the machine during normal handling. If you do not have the original case, a padded camera bag or small hard-sided suitcase works well. The machine should not shift inside the bag during turbulence or when the bin closes.
Pack your power cord and any adapters in the same bag as your machine. If you are traveling to a country with different electrical outlets, bring a voltage converter or dual-voltage power supply — many newer CPAP machines are dual-voltage, but check your manual first. Include any replacement filters, tubing, or mask parts you might need during your trip, since these are not always available at your destination.
Do not wrap your CPAP in plastic bags or plastic wrap. Moisture can become trapped inside, leading to mold growth on the machine and tubing. If you are concerned about dust or spills, use a breathable fabric bag instead.
Packing your CPAP in checked luggage safely
If you must check your CPAP, use a hard-sided protective case with at least 2 inches of padding on all sides. Wrap the machine itself in bubble wrap or foam padding, and fill empty spaces in the case with soft items like socks or towels. Do not use newspaper or crinkled paper, which can shift during handling and leave your machine exposed.
Place the case in the center of your checked bag, surrounded by soft clothing. Avoid packing it near the edges or corners, where baggage handlers are more likely to drop or crush it. If your airline allows it, mark the bag as fragile and request careful handling — this does not may provide protection, but it signals to handlers that the contents are delicate.
Consider purchasing additional baggage insurance through your airline or a third-party provider. Standard baggage coverage often does not fully cover high-value medical equipment, and a claim for a damaged CPAP can take weeks to process.
Humidifier tanks and water during travel
If your CPAP includes a heated humidifier, empty the water tank completely before packing. Do not leave any standing water inside the tank or tubing. Moisture can promote mold growth, and water can leak onto your machine or other belongings during flight.
Let the humidifier chamber air-dry for at least 2 hours before packing. If you want to use the humidifier during your trip, fill the tank with distilled water once you arrive at your destination. Tap water can leave mineral deposits inside the chamber, reducing the humidifier's effectiveness over time.
What airlines say about CPAP machines
Most major U.S. airlines — including Delta, United, American, and Southwest — do not count CPAP machines toward your carry-on bag limit. You can bring your CPAP as a medical device in addition to your standard carry-on bag and personal item. Check your specific airline's website or call before you travel, since policies can change and smaller regional carriers may have different rules.
Some airlines ask that you notify them in advance if you are traveling with medical equipment, though this is not required by law. Notifying the airline can help if there are questions at the gate, and it ensures the crew knows you have a medical device on board.
Traveling across time zones with your CPAP
When you cross time zones, your sleep schedule shifts, but your CPAP settings do not need to change. Use your machine at the same time you would at home, adjusted for local time at your destination. If you arrive in the morning after an overnight flight, you may not need your CPAP until that evening — use local time to decide when to set it up.
If you are traveling for more than a few days, bring extra supplies: replacement mask cushions, a backup power cord, and extra filters. Medical supply stores at major airports and hotels can sometimes provide these items in an emergency, but it is faster and cheaper to pack them yourself.
Frequently Asked Questions
Will the cabin pressure damage my CPAP machine?
No. Airplane cabins are pressurized to the equivalent of 6,000 to 8,000 feet of altitude, which does not harm CPAP machines. The machine will function normally when you land and use it that night. Temperature changes during flight also do not damage the equipment.
Can I use my CPAP on the airplane?
Most airlines do not allow you to use electrical devices during flight, including CPAP machines. You can use your machine in the airport terminal before boarding, and you can set it up in your hotel or destination once you land. Some airlines may allow use during long layovers if you remain in the terminal.
What if my CPAP gets damaged during checked baggage handling?
Report the damage to the airline when ready at baggage claim, before you leave the airport. Ask for a written incident report and take photos of the damage. File a claim with the airline's baggage department within the timeframe listed on your ticket — usually 14 to 21 days. If you purchased additional baggage insurance, file a claim with that provider as well.
Do I need a doctor's letter to travel with my CPAP?
You do not need a letter for domestic U.S. travel. For international travel, some countries request a doctor's letter or prescription as proof the machine is for personal medical use. Check the customs rules for your destination before you leave, and carry your prescription or a letter from your doctor if required.
Can I pack my CPAP with my other electronics?
You can pack it near other electronics in your carry-on, but keep it separate from items that could shift and damage it — like laptops or tablets. If you are checking your CPAP, pack it away from other heavy electronics. Your machine is more fragile than most devices and needs its own protected space.
