Flying with Your CPAP Machine: The Complete Guide for Canadians

Flying with your CPAP machine in Canada is more straightforward than most people expect. However, it does raise a lot of questions. Does your CPAP go in carry on or checked luggage? What do you need for international flights? Can you use it on the plane? This guide answers all of those questions clearly, so you can travel with confidence and never miss a night of therapy.

Can You Bring a CPAP Machine on a Plane in Canada?

Yes. CPAP machines are classified as medical devices, not consumer electronics. Therefore, most airlines allow them on board without counting them as part of your carry on allowance. This applies to flights within Canada and most international routes as well.

The Canadian Air Transport Security Authority (CATSA) allows CPAP machines through security screening. However, you will need to remove it from your bag and place it in a separate bin for X ray screening. Additionally, the water in your humidifier must be emptied before going through security.

Most airlines follow similar rules. That said, policies vary between carriers, so it is always worth confirming directly with your airline before you travel. Give them at least two weeks notice for any special medical equipment requirements.

Should You Pack Your CPAP in Checked Luggage or Carry On?

The short answer is carry on, always. Checked luggage gets handled roughly, delayed, and occasionally lost. Because your CPAP machine is both a medical device and expensive equipment, putting it in the cabin with you is the safest option.

Most airlines specifically allow CPAP machines as a free additional item beyond your standard carry on. However, policies differ, so confirm this with your airline when booking. Some carriers require documentation to waive the extra bag fee.

If you absolutely must check your CPAP, use a hard sided case, remove the water chamber, and wrap the machine carefully. That said, we strongly recommend keeping it with you in the cabin whenever possible.

What Documents Do You Need When Flying with Your CPAP Machine?

Most airlines and security agencies do not require documentation for CPAP machines. However, carrying a letter from your physician or Sleep Clinician is strongly recommended. It confirms that the device is medically necessary and can prevent delays at security or when checking in.

For international travel, a physician letter becomes even more important. Some countries have stricter rules around medical devices at customs. Additionally, if you are flying to the United States, the TSA recommends carrying your prescription and device documentation even though it is not technically required.

Ask your Sleep Clinician at Ontario Sleep Care to prepare a travel letter for you before your trip. This takes only a few minutes and can save you significant hassle at the airport.

How to Pack Your CPAP for Air Travel

Packing your CPAP correctly protects the machine and makes security screening faster. First, empty the water chamber completely and leave it out to dry before packing. Water in the humidifier is not permitted through security and can spill during the flight.

Second, pack your mask, tubing, and power cord in a dedicated CPAP travel bag. These are available at Ontario Sleep Care and keep your equipment organized and easy to access at security. Many travel bags are designed to fit under the seat in front of you, which is ideal for overnight flights.

Third, bring your power adapter if you are travelling internationally. CPAP machines typically run on 100 to 240 volts, but you will need the right plug adapter for your destination. Check your machine’s voltage range before you leave.

Using Your CPAP Machine on the Plane

Many modern aircraft have in seat power outlets that are compatible with CPAP machines. However, this is not guaranteed on all airlines or aircraft types. Therefore, it is worth checking with your airline whether power is available at your seat.

If power is not available, a CPAP battery pack is the best solution. Dedicated CPAP batteries are designed to run the machine for one or two nights on a single charge. They are approved for carry on use by both the FAA and CATSA. However, they cannot go in checked luggage, so always pack them in your carry on bag.

Some airlines also require advance notice if you plan to use your CPAP during the flight. Contact the airline at least 48 hours before departure to confirm their requirements.

Tips for Flying with Your CPAP Machine Internationally

Flying with your CPAP machine internationally requires a little more preparation than domestic flights. However, with the right steps in place, it is straightforward.

First, check the voltage requirements at your destination. Most modern CPAP machines are dual voltage, but always verify before you travel. Second, bring distilled water for your humidifier if possible. Tap water in many countries contains minerals that can damage the humidifier over time. Bottled distilled water works as an alternative if you cannot bring your own.

Third, consider a travel sized CPAP machine if you travel frequently. These are lighter and more compact than standard machines, making them easier to carry. Your Sleep Clinician at Ontario Sleep Care can advise you on travel CPAP options that fit your prescription.

Finally, give yourself extra time at the airport. Security screening with medical equipment can occasionally take longer than expected. Arriving early removes that stress entirely.
