Sleep Apnea and Air Travel: What You Need to Know Before You Fly
Travelling by air is an exciting experience, whether you are flying for business, a holiday, or to visit family. If you have obstructive sleep apnea (OSA), you may wonder whether flying is safe, whether you should carry your CPAP or BiPAP machine, or whether sleeping on a flight could cause problems.
The good news is that most people with obstructive sleep apnea can travel safely by air. With appropriate planning and by continuing your prescribed treatment, most journeys can be completed without difficulty. Understanding how air travel affects sleep apnea and knowing how to prepare before your trip can help make your journey safer and more comfortable.
Can People with Sleep Apnoea Fly?
Yes. Most patients with obstructive sleep apnea can safely travel on commercial aircraft.
Aircraft cabins are pressurized, although the oxygen level inside the cabin is still lower than at sea level. Most people with well-controlled sleep apnea tolerate this without difficulty.
However, if you also have significant lung disease, heart disease, obesity hypoventilation syndrome, or require long-term oxygen therapy, you should discuss your travel plans with your healthcare provider before flying. In some cases, additional assessment may be recommended.
Should You Travel with Your CPAP or BiPAP?
If you use Positive Airway Pressure (PAP) therapy, whether a CPAP (Continuous Positive Airway Pressure) or BiPAP (Bilevel Positive Airway Pressure) machine, you should generally travel with your device.
Many patients consider leaving their machine at home for convenience, particularly during short trips. However, missing several nights of treatment may result in:
- Poor quality sleep
- Excessive daytime sleepiness
- Morning headaches
- Fatigue
- Reduced concentration
- Increased snoring
- Worsening sleep apnea symptoms
If you routinely use your PAP device at home, you should continue using it while travelling whenever possible.
Should You Choose a Daytime Flight?
Whenever practical, consider booking a daytime flight rather than an overnight flight.
During daytime travel, you are less likely to fall asleep, reducing the need to use your CPAP or BiPAP machine during the flight.
On overnight or long-haul flights, where sleep is more likely, continuing your prescribed PAP therapy is preferable if the airline permits its use.
This recommendation is consistent with guidance from the British Thoracic Society, which advises that daytime travel may be more suitable for patients who depend on PAP therapy during sleep.
Can You Use CPAP or BiPAP During a Flight?
Many airlines allow passengers to use CPAP or BiPAP machines during flights, particularly on long-haul journeys. However, airline policies vary considerably.
Before booking your flight or travelling, contact your airline and ask:
- Is CPAP or BiPAP permitted during the flight?
- Does the aircraft provide power for medical devices?
- Is a battery-powered device required?
- Are there restrictions on lithium batteries?
- Is a medical clearance form or doctor’s letter required?
Do not assume every airline has the same policy. Confirming these details well before your departure can help avoid unnecessary problems at the airport.
Carry Your PAP Device in Your Hand Luggage
Your CPAP or BiPAP machine is an essential medical device and should always travel in your hand luggage rather than your checked baggage.
Keeping it with you reduces the risk of damage, loss, or delays and ensures it is available if needed during the journey.
If you are travelling internationally, carrying a copy of your prescription or a doctor’s letter may also be helpful, particularly if requested by airport security or airline staff.
What Happens at Airport Security?
CPAP and BiPAP machines are recognized medical devices and routinely pass through airport security screening.
You may be asked to remove the device from its carrying case for inspection, similar to a laptop computer.
Allowing a little extra time at the airport can make the screening process less stressful.
Is It Safe to Sleep on the Plane?
If you usually require CPAP or BiPAP whenever you sleep, you should aim to continue using it during overnight flights if the airline permits.
If using your device is not possible, try to avoid prolonged periods of sleep during the flight whenever practical.
You should also avoid alcohol and sleeping tablets before and during the flight unless specifically advised by your doctor. Both can relax the muscles of the upper airway, worsen obstructive sleep apnea, and increase the likelihood of breathing interruptions while asleep.
Stay Well Hydrated During Your Journey
Aircraft cabins have very low humidity, which can dry the nose, throat, and airways.
To remain comfortable during your journey:
- Drink water regularly.
- Limit excessive caffeine.
- Avoid excessive alcohol.
- Continue using your humidifier after arrival if this forms part of your usual PAP therapy.
Maintaining good hydration can help reduce airway irritation during and after your flight.
What If You Also Need Oxygen?
Most people with obstructive sleep apnea do not require oxygen during air travel.
However, some patients also have other respiratory conditions such as COPD, pulmonary fibrosis, or obesity hypoventilation syndrome that may increase their oxygen requirements.
If your doctor believes you may need oxygen while flying, additional assessment before travel may be recommended, and oxygen arrangements can usually be coordinated with the airline.
It is important to remember that CPAP or BiPAP therapy and oxygen therapy are different treatments. Using one does not automatically mean you require the other.
Adjusting to Different Time Zones
Travelling across multiple time zones may temporarily disturb your normal sleep routine.
To minimize disruption:
- Continue using your CPAP or BiPAP every night.
- Gradually adjust to local sleeping hours.
- Allow yourself time to recover from jet lag.
- Maintain a regular sleep schedule as much as possible.
Most travelers adjust within a few days.
When Should You Speak to Your Doctor Before Flying?
Arrange a medical review before travelling if you:
- Have recently been diagnosed with sleep apnea.
- Have severe daytime sleepiness despite treatment.
- Have significant heart or lung disease.
- Use oxygen therapy.
- Have recently been admitted to hospital.
- Are unsure whether your condition is stable enough for travel.
- Need advice regarding CPAP or BiPAP use during your journey.
A pre-travel consultation allows any concerns to be addressed before departure and helps ensure your treatment is optimized.
Travel with Confidence
Having obstructive sleep apnea should not prevent you from enjoying air travel. Most patients can fly safely with careful planning and by continuing their prescribed PAP therapy.
Before you travel, check your airline’s requirements, carry your CPAP or BiPAP machine in your hand luggage, avoid alcohol and unnecessary sedatives, and consider choosing daytime flights whenever practical. If you have additional lung or heart conditions, speak to your healthcare provider before your journey.
A little preparation before you fly can help ensure a safer, more comfortable trip and allow you to arrive at your destination feeling well rested.
