The short answer. A fit to fly certificate is a letter from a doctor confirming you are medically safe to travel by air. There is no UK law that requires one — each airline sets its own rule, and the rules genuinely differ. The most common triggers are pregnancy from week 28, recovery from an infectious illness such as chickenpox, and a recent injury, operation or medical event.
When airlines ask for one
Four situations account for almost every fit to fly certificate issued in the UK.
Pregnancy. Most airlines want a letter from week 28, and most stop carrying you altogether somewhere between week 34 and week 37. The cut-offs are not standardised — Wizz Air stops at 34 weeks, easyJet at the end of week 35, British Airways and TUI at the end of week 36. Full rules by week and airline.
Infectious illness. Chickenpox is the big one. Airlines will not carry a visibly infectious passenger, and several want written confirmation that you are past the infectious stage before they let you board. What the airlines actually require.
Recent illness, injury or surgery. A cast fitted in the last 48 hours, a recent operation, a heart attack, a stroke, a chest infection — any of these can prompt check-in staff to ask whether a doctor has cleared you. Recovery times by procedure.
Cancelling, not flying. Sometimes the honest answer is that you are not fit to travel. In that case the letter you need is the opposite one — medical evidence for a refund or an insurance claim. Not fit to fly certificates.

NHS or private?
Fit to fly letters sit outside the NHS GP contract. That single fact explains most of the confusion people run into. Your practice is not refusing to help out of awkwardness — writing the letter is private work, so the surgery can decline it, or charge a private fee and put you in a queue.
In practice that means an NHS route is possible but unpredictable: some practices do it for around £30 to £50 within a week or two, many will not do it at all, and almost none will turn one around in a day. If you are flying soon, that timing risk is the thing to weigh.
A full comparison of the two routes, including what to ask your surgery and what to do if they say no.
Before you pay for anything: Whichever route you take, the letter must come from a registered doctor and must say what your airline asks it to say. A generic “patient is well” note is the single most common reason a certificate gets rejected at check-in.
Common questions
What is a fit to fly certificate?
A fit to fly certificate is a short letter signed by a doctor confirming that you are medically well enough to travel by air. Airlines ask for one when something about your health could affect the flight — most commonly pregnancy after week 28, recovery from an infectious illness such as chickenpox, or a recent injury, operation or medical event. It is not a test and not a vaccination record. It is a clinical opinion, on headed paper, that you are safe to fly.
How do I get a fit to fly certificate in the UK?
You can ask your own GP, or use a private online GP service. NHS GPs are not obliged to issue them, and many practices either decline or charge a private fee with a wait of one to two weeks. A private service reviews your details and returns a signed letter, usually the same day. Either way the letter must come from a registered doctor — you cannot write one yourself.
Can I get a fit to fly certificate from the NHS?
Not as an NHS service. Fit to fly letters fall outside the NHS GP contract, so a practice that agrees to write one is doing private work and can set its own fee. Many decline altogether, which is why most people end up using a private provider. We compare the two routes here.
How much does a fit to fly certificate cost?
Private fit to fly certificates in the UK generally run from about £25 to £100 depending on the provider and how quickly you need it. Ours start at £67. A GP practice doing it as private work will typically charge a similar amount, but usually takes longer.
How long is a fit to fly certificate valid for?
There is no single expiry date — the airline sets the window. Ryanair wants the letter dated within two weeks of the flight, Jet2 within seven days of the outbound leg, Qatar Airways within ten days, Wizz Air within six days and Air India within 72 hours. British Airways and Emirates simply say “as close to travel as possible”. Check your airline’s window before you book the appointment, or you may need a second letter.
Do I actually need one, or is my airline being awkward?
It depends entirely on the airline. There is no UK law requiring a fit to fly certificate — each airline sets its own rule in its conditions of carriage, and they genuinely differ. easyJet, for example, asks for no certificate at any stage of an uncomplicated pregnancy, while Ryanair requires one from week 28. Check your airline’s rule here before you pay for anything.
What if the doctor decides I am not fit to fly?
Then you get a letter saying so, and that letter has real value. A not fit to fly certificate is the medical evidence airlines, tour operators and travel insurers ask for when you need to cancel or claim. You are not charged twice.
Will the airline definitely accept it?
A letter from a GMC-registered doctor on headed paper, containing what the airline asks for and dated inside its window, is what airlines are looking for. Some carriers — Ryanair, British Airways, Jet2 and Qatar Airways among them — publish their own form and prefer it completed. We can complete the airline’s own form where one exists; tell us the carrier when you book.
