Did you know that more than nine in ten British adults (92%1) are planning a holiday abroad in the next 12 months? If you’re among those hoping to travel this year, and you have a pre-existing medical condition, you may require a letter from your doctor confirming your fitness to fly. Below, we’ve outlined everything you need to know.
What is a fit-to-fly certificate and when do you need one?
A standard fit-to-fly letter indicates that a doctor has deemed it safe for you to travel by plane. This means your medical conditions have been assessed and are not expected to be adversely affected by flying.
Airlines can request medical clearance if you are:
- recently discharged from a hospital
- recovering from an operation
- more than 28 weeks pregnant
Certificates might be necessary for travellers with a wide range of conditions – from broken bones to cancer. So, if in any doubt, you should consult your airline as far in advance as possible.
After the 28th week of pregnancy, most airlines require confirmation that you are able to travel. Your GP or midwife must confirm:
- you are healthy
- your pregnancy is normal
- the expected date of delivery
Some airlines may also require a more detailed form about your health status. British Airways, for example, often seek clarification on whether you travel with medical devices or need additional oxygen. Make sure you start this process well in advance for peace of mind.
How much does it cost to get one?
The cost of a fit-to-fly certificate varies by GP surgery and region. These fees should be listed on your surgery’s website and typically range from around £20-40.
How long is your certificate valid for?
You must provide current written confirmation of your fitness to fly at the time of your trip. A letter from six months ago will not be sufficient.
If you have a long-term condition, you will likely need to update this letter each time you travel, as your health status may have changed. The airline can refuse boarding if they deem your documentation outdated.
Frequently asked questions
Can you fly if you have had recent surgery?
You can fly as long as your doctor is confident it won’t affect your recovery. The time you need to wait after any surgery will depend on the type of treatment.
Keyhole surgery might only require a few days, but major chest or abdominal surgery will need more time to heal before you travel.
What if you have a heart condition?
Most heart conditions can be affected by flying, due to changes in pressure. However with good management this should not stop you from travelling. Make sure you discuss any holiday plans with your GP and ask their advice.
Can you travel with your arm in a cast?
A new cast can impact circulation, so most airlines will not allow you to fly if the cast has been on for less than 48 hours. If you need to travel within this period, you may need to have the cast split, which can be done by the fracture team. You will need to replace the cast upon arrival.
