Yes, you can pack your CPAP machine in checked luggage, but carry-on is safer

Your CPAP machine can go in checked baggage, but the Transportation Security Administration (TSA) allows it in carry-on bags too — and carry-on is the better choice. Checked luggage gets thrown, crushed, and exposed to pressure changes that can damage sensitive equipment. Your CPAP is expensive and you need it to sleep, so keeping it with you makes sense.

If you do check it, pack it in its original hard case or a padded travel case, surrounded by soft items like clothing or towels. Wrap the tubing, mask, and power cord separately so they don't get tangled or pinched. Label the case clearly with your name and contact information in case it gets separated from your other bags.

The TSA does not count your CPAP machine toward your carry-on bag limit if you bring it separately, which means you can bring your regular roller bag plus your CPAP case without penalty. This is one of the few medical devices that gets this exception.

Key Takeaways

  • Your CPAP machine is allowed in both carry-on and checked luggage, but carry-on protects it from damage during baggage handling.
  • Pack your CPAP in a hard case or padded travel case with soft padding around it, and wrap cords and tubing separately to prevent tangling.
  • The TSA does not count your CPAP as a carry-on bag, so you can bring it in addition to your regular luggage without extra fees.
  • Bring your power adapter and a backup mask in your carry-on bag in case your checked luggage is delayed.
  • Notify your airline ahead of time that you are traveling with medical equipment so staff can note it in your reservation.

Packing your CPAP for carry-on travel

If you bring your CPAP in the cabin, place it in your carry-on bag or a separate medical equipment bag. The TSA allows you to keep it in its case during X-ray screening — you do not have to remove it. Tell the TSA officer at security that you have a medical device so they know what they are looking at on the scanner.

Pack your power cord, tubing, and mask in the same bag so everything stays together. If your CPAP uses a humidifier, empty it completely before travel — you cannot bring water through security, and a wet humidifier can leak and damage other items. Fill it with distilled water once you reach your destination.

Keep your CPAP in the cabin during flight rather than stowing it in the overhead bin if possible. Cabin pressure changes can affect the machine, and overhead bins get cold at altitude. If you must use the overhead bin, wrap your CPAP in extra padding first.

What to do if you check your CPAP instead

Checked luggage is rougher on equipment, but your CPAP can survive the trip if you pack it correctly. Use the original hard case from the manufacturer if you still have it — these are designed to protect the machine during transport. If you no longer have the original case, buy a padded travel case made specifically for CPAP machines; these cost between $30 and $80 and are worth the investment.

Line the bottom of the case with soft items like rolled-up socks, underwear, or a small towel. Place your CPAP machine in the center, then surround it completely with more soft padding. Wrap your tubing, mask, and power cord in separate plastic bags or pouches so they do not press against the machine or each other.

Close the case and place it in the center of your checked bag, surrounded by more clothing for cushioning. Do not pack it on top of heavier items or at the edge of your suitcase where it can shift during handling. Tape a "Fragile" sticker on the outside of your checked bag if your airline provides them.

Power and adapter considerations for international travel

If you are traveling outside the United States, check the voltage and outlet type at your destination before you leave. Most CPAP machines sold in the US run on 110-120 volts, but many countries use 220-240 volts. Using the wrong voltage will destroy your machine.

Buy a voltage converter rated for your CPAP's wattage — the manual lists this information, usually between 60 and 90 watts. A converter that is too weak will not power the machine properly. Alternatively, some CPAP manufacturers sell dual-voltage machines that work on both 110-120 and 220-240 volts; if you travel internationally often, this may be worth the extra cost.

You will also need a plug adapter to fit your machine's cord into the outlet shape used in your destination country. Plug adapters are cheap (usually $5 to $15) and small enough to pack easily. Buy one before you travel rather than hunting for one at the airport.

Notifying your airline and TSA PreCheck considerations

Call your airline at least 48 hours before your flight and tell them you are traveling with a CPAP machine. Most airlines have no restrictions on CPAP travel, but notifying them in advance prevents confusion at the gate and ensures staff know you have medical equipment. Write down the name of the person you spoke with and the time of the call in case you need to reference it later.

If you have TSA PreCheck, you can keep your CPAP in its case during security screening and do not have to remove shoes, belts, or light jackets. This speeds up the process, though you still need to place your bag through the X-ray machine. TSA PreCheck costs $78 to $85 for five years and is worth considering if you travel more than twice a year for any reason.

What happens if your CPAP gets damaged or lost

If your checked CPAP arrives damaged, file a damage claim with the airline before you leave the airport. Take photos of the damage and the broken machine, and keep all packaging materials. Airlines typically cover damage to checked baggage up to a certain amount, though the exact limit varies by carrier — check your airline's website for their specific policy.

If your CPAP is lost, the airline will search for it while you are traveling. In the meantime, contact your sleep doctor or the equipment supplier who provided your machine and explain that you need a replacement urgently. Many suppliers keep loaner machines available for travelers in this situation, or they can arrange an overnight shipment to your hotel. Do not skip CPAP use while traveling — the disruption to your sleep can affect your health and your ability to function.

Traveling with a backup mask and supplies

Pack at least one backup mask in your carry-on bag, separate from your main CPAP equipment. If your primary mask gets lost or damaged, you have a way to use your machine that night. Masks are smaller and lighter than the full machine, so this takes almost no space.

Bring extra tubing connectors, a spare power cord if your machine uses a removable one, and a small bottle of distilled water for the humidifier. These items weigh almost nothing and can save you from a sleepless night if something breaks or gets forgotten. Pack them in a small toiletries bag so they stay organized and straightforward to find.

If you are traveling for more than a week, bring enough mask cushions and filters for the entire trip. Filters get dirty with use and should be replaced every 30 days, so a long trip may require a fresh filter. Check your machine's manual for the recommended replacement schedule before you pack.

Frequently Asked Questions

Will airport security confiscate my CPAP machine?

No. The TSA recognizes CPAP machines as medical devices and allows them through security in both carry-on and checked bags. You do not need a doctor's note or prescription letter, though having one does not hurt. Tell the TSA officer you have a medical device when you reach the scanner.

Can I use my CPAP on the airplane?

Most airlines allow you to use your CPAP during flight if you have a seat-level power outlet, which is rare on domestic flights. International long-haul flights sometimes have power ports in business and first class. Check with your airline before booking to see if power is available on your specific flight. If not, you can skip one night of CPAP use without serious harm, though you may sleep poorly.

What if my CPAP machine gets wet during travel?

Do not use it until it is completely dry. Unpack it when ready and let it air-dry for at least 24 hours in a warm, dry room. Do not use a hair dryer or place it in direct sunlight, as heat can damage the electronics. If water got inside the machine, contact the manufacturer or your equipment supplier for guidance before turning it on.

Do I need to tell my doctor I am traveling with my CPAP?

You do not need permission, but it is helpful to mention your travel plans at your next appointment. Your doctor can confirm your prescription is current and may provide a letter stating you use CPAP therapy, which can be useful if you need to replace your machine during travel or if you have questions at security.

Can I pack my CPAP humidifier with water in it?

No. You cannot bring water through TSA security, and a full humidifier can leak and damage your machine or other luggage. Empty the humidifier completely before packing, and fill it with distilled water once you reach your destination. Most hotels have distilled water available, or you can buy a small bottle at a drugstore.
