Get Fit to Fly medical certificate

A Fit to Fly medical certificate is a document stating that, based on a medical review, air travel is medically appropriate for you. It is usually requested when you have recently been unwell or treated, or when a condition could worsen during a flight due to cabin pressure, lower oxygen levels, long sitting times, or limited access to medical help onboard.

The certificate typically includes your name, the assessment date, a short medical conclusion that you are fit to fly, and a digital signature. Many airlines accept this in digital format.

Airlines may ask for a Fit to Fly certificate in situations like these:

• You had a recent respiratory infection and still have symptoms such as cough, fever, shortness of breath, or chest discomfort.
• You recently had surgery or a procedure and the airline needs confirmation that flying is appropriate.
• You have a chronic condition that has recently changed, for example flare-ups of asthma, heart problems, or other conditions where travel could increase risk.
• You are travelling with visible symptoms, medical devices, or mobility limitations and airline staff needs medical confirmation before boarding.

Some airlines request the certificate at check-in, while others ask for it in advance through their medical desk. That is why timing matters.

No. A Fit to Fly certificate supports your case, but the airline makes the final decision. Airlines have their own safety rules, and staff may refuse boarding if they believe flying could be unsafe, even if a certificate is provided. This can happen if symptoms worsen, if the certificate is too old, or if the airline requires a specific form.

Think of the certificate as medical confirmation, not a boarding pass.

Many airlines require the Fit to Fly certificate to be recent, often issued within 24 to 72 hours before departure. The exact timeframe depends on the airline and the reason the certificate is requested.

If you are travelling soon, it is smart to check your airline’s guidance first, then request the certificate close enough to departure to meet the timing rules.
