Flying with Lung Cancer: Cabin Pressure and Oxygen Needs
August 27, 2026
Planning a trip while living with lung cancer can come with a few extra things to think about, particularly if you’re flying.
You might be wondering whether cabin pressure could affect your breathing, what flying might feel like if you already experience breathlessness, or whether you could need oxygen during your journey.
For many people with lung cancer, flying is still possible. What matters is understanding what is right for you, speaking to your healthcare team and giving yourself plenty of time to prepare.
Why can cabin pressure affect your breathing?
An aircraft cabin is pressurised, but the air pressure is lower than it is on the ground.
According to the UK Civil Aviation Authority (CAA), commercial aircraft typically have a cabin altitude equivalent to around 5,000 to 8,000feet, which means there is a little less oxygen available than at sea level.
For many people, this change does not cause any difficulties. However, if lung cancer, treatment or another lung condition has affected your breathing or lung function, flying may feel different for you.
This doesn’t necessarily mean you can’t fly. Your healthcare team can help you understand how flying may affect you and whether you need any extra support or arrangements for your journey.
How do I know if I might need oxygen when flying?
Not everyone living with lung cancer will need oxygen when they fly. Whether you do will depend on your individual health and how your breathing is affected.
Your healthcare team may consider things such as:
- How breathless you currently feel.
- Your usual oxygen levels.
- How well your lungs are working.
- Any other lung or heart conditions you have.
- Treatment you are currently receiving.
- Whether you have recently had chest surgery.
If they feel it would be helpful, they may recommend a fit-to-fly assessment or a hypoxic challenge test before you travel.
A hypoxic challenge test recreates the lower oxygen levels you may experience in an aircraft cabin while your oxygen levels are monitored. This can help your healthcare team understand how flying may affect you and whether you could benefit from additional oxygen during the journey.
You don’t have to make these decisions alone. Speak to the healthcare team who knows your circumstances, as they can advise you on what may be right for you before you fly.
What if I already use oxygen?
Using oxygen at home does not necessarily mean that flying is out of the question.
Before making your travel plans, speak to your healthcare team about whether flying is suitable for you and whether you may need oxygen during the journey.
It is also a good idea to contact your airline as early as possible, as arrangements for travelling with oxygen can vary. Depending on the airline they may:
- Provide oxygen during the flight.
- Allow certain approved portable oxygen concentrators.
- Require medical information or a MEDIF form.
- Require advance notice.
- Charge for providing oxygen.
If you already use oxygen or need to travel with medical equipment, checking the airline’s requirements before you book can help you understand what arrangements need to be made and avoid any surprises closer to your trip.
Can I fly after lung cancer surgery?
If you have recently had chest or lung surgery, it is important to speak to your healthcare team before making plans to fly.
Changes in cabin pressure can matter after some types of surgery, particularly if there is any trapped air around the lung. Macmillan recommends getting medical advice before flying following recent chest surgery.
There is no single waiting period that will be right for everyone. Your recovery is individual, and your surgeon or cancer team can advise you based on things such as:
- The type of operation you have had.
- How your recovery is progressing.
- Whether you have experienced any complications.
- Your breathing and oxygen levels.
- The journey you are planning.
Everyone recovers differently, so the right time to fly will be personal to you. Your healthcare team can help you understand when travelling may be suitable and whether there is anything extra you need to consider before your journey.
A few things to arrange before your flight
A little preparation before your journey can help make travelling feel more manageable and give you time to arrange any extra support you may need.
Before you travel, it may help to:
- Speak to your cancer or respiratory team about your travel plans and any concerns you have about flying.
- Ask whether you need a fit-to-fly assessment or additional oxygen for your journey.
- Contact your airline early if you are travelling with oxygen or other medical equipment.
- Keep essential medication in your hand luggage so it is easy to access during your journey.
- Consider airport assistance if breathlessness, fatigue or reduced mobility could make getting around the airport more difficult.
- Check your travel insurance reflects your current health, including any treatment, medication or changes in your medical circumstances.
Giving yourself a little extra time to plan can help you understand what support is available and what arrangements may be right for you.
Flying should be about where you are going
Living with lung cancer can mean there is a little more to think about when planning a flight. Although, that does not necessarily mean travel has to be off the table.
A trip might mean discovering somewhere new, spending time with people you love, or simply having something enjoyable to look forward to.
At Lighthouse, we believe travel can still be an important part of life. With the right medical advice and a little extra planning, you can understand what is right for you and make the arrangements you may need.
Then, when you are ready, you can focus a little more on where you are going — and a little less on getting there.
