How To Appeal A Denied Fit To Fly Certificate
Being denied a fit-to-fly certificate is frustrating, but in most cases it is not the end of the road. Doctors decline to issue fit-to-fly certificates for clear clinical reasons — and understanding those reasons is the first step to resolving the situation. Whether you disagree with the clinical assessment, believe new information was not considered, or simply want a second opinion, this guide explains your options.
It is important to approach this with the right mindset: a doctor refusing to issue a certificate is making a clinical judgment intended to protect your health, not being obstructive. The most productive path is to understand the specific reason for the refusal, address it with additional evidence or assessment, and then seek a new assessment rather than trying to overturn a clinical decision.
Common Reasons a Fit-to-Fly Certificate Is Refused
| Reason for Refusal | What This Means | What You Can Do |
|---|---|---|
| Insufficient waiting time since surgery or procedure | Standard minimum waiting periods have not elapsed (e.g. 7 days post-MI, 2 weeks post-pneumothorax) | Wait the required period and apply for a new certificate; book closer to the travel date |
| Active infection or contagious illness | Infectious condition that poses risk to other passengers | Wait until the condition resolves and obtain a clearance certificate |
| Uncontrolled medical condition | Condition (hypertension, cardiac failure, severe anaemia) not adequately managed | Address the underlying control issue with your specialist; return for reassessment once controlled |
| Pregnancy complication | Placenta praevia, pre-eclampsia, or other condition creating unacceptable flight risk | Seek specialist obstetric review; obtain documentation of management plan; reassess |
| Incomplete medical history provided | Doctor could not make a full assessment without complete information | Obtain relevant medical records and attend a more comprehensive consultation |
| Condition genuinely preventing safe travel | The clinical risk of flying is real and the refusal is correct | Accept the decision; claim on travel insurance using the refusal as evidence |
Steps to Take After a Refusal
- Ask for the specific reason — you are entitled to know why the certificate was refused. Ask the doctor to document the clinical reason clearly. This helps you identify whether the refusal is based on a temporary factor (waiting period, current infection) or a more fundamental concern.
- Obtain your relevant medical records — if the refusal was due to incomplete information, request your GP records and any specialist correspondence, then attend a new consultation with the full picture.
- Seek a second opinion — you are always entitled to consult a different doctor. If you believe the refusal was based on an error, a second GMC-registered doctor can reassess independently. Be transparent about the previous refusal — a doctor who makes an assessment without knowing about a prior refusal may reach a different conclusion on incomplete information.
- Address the underlying issue — if the refusal was because your blood pressure is uncontrolled or your condition is unstable, the correct response is to optimise treatment and seek reassessment, not simply find a different doctor who will overlook the same issue.
- Consult a specialist if appropriate — for cardiac or respiratory refusals, a specialist consultation with a cardiologist or respiratory physician may resolve the uncertainty and provide clearance that a GP alone cannot give.
- Claim on your travel insurance — if flying is genuinely not safe, the refusal certificate (or written documentation from your doctor confirming you are not fit to fly) is the medical evidence your insurer needs to process a cancellation claim.

Using a Refusal for a Travel Insurance Claim
A fit-to-fly refusal is valuable evidence for a travel insurance claim. Most comprehensive travel insurance policies cover cancellation where a doctor has certified that you are not fit to fly. You do not need to provide the certificate itself — a letter from your doctor stating that they were unable to certify you as fit to fly, and the reason, is sufficient for most insurers.
What to Request from Your Doctor
Ask your doctor to provide a letter on their headed paper (or via an official digital letterhead) confirming: (1) your name and date of birth, (2) the medical reason they were unable to certify you as fit to fly, (3) the dates of your planned travel, (4) that you were unfit to travel on those dates. This is not the same as a fit-to-fly certificate — it is a not-fit-to-fly letter, and it is what insurers require for cancellation claims.
Frequently Asked Questions
Can I appeal directly to the airline if a doctor refuses a certificate?
Airlines do not override clinical decisions — they cannot require a doctor to issue a certificate the doctor believes is clinically inappropriate. If a doctor has refused to certify you, the airline will accept that decision. Your recourse is to seek reassessment (possibly with additional specialist input) from a different doctor, not to appeal to the airline. If you are denied boarding for a different reason (e.g. the certificate format was not accepted), that is a separate issue and can be appealed with the airline.
What if I think the doctor made a mistake?
You are entitled to a second opinion. If you believe the first doctor was working with incomplete information, or made a clinical error, seek a second assessment from a different registered practitioner and provide the most complete medical history possible. If you believe the first doctor acted negligently or unprofessionally, you can raise a complaint with the GMC — but this does not change the immediate situation regarding your travel plans.
Will a refusal affect my future ability to get a fit-to-fly certificate?
No — a refusal at one point in time does not create a permanent record that prevents future certificates. If your condition improves, the underlying issue is resolved, or sufficient time passes (e.g. after a waiting period post-surgery), a doctor can certify you fit to fly at that later point. Certificates are assessments of your fitness at a specific time, not lifetime determinations.
Can I fly anyway if a doctor refuses to certify me?
Technically, airlines check certificates at certain gestational ages and for some specific conditions (e.g. pregnancy, recent surgery), but they do not check for all conditions. However, flying against medical advice creates serious risks: your travel insurance may be invalidated if you travel against medical advice; you could experience a medical emergency in flight without adequate care available; and you may be placing other passengers at risk if your condition is contagious. The doctor’s refusal exists for your protection — treating it as an inconvenience to be bypassed rather than clinical advice is a significant risk.
How long after a refusal can I reapply for a certificate?
This depends entirely on the reason for refusal. If the refusal was due to a minimum waiting period (e.g. 7 days post-MI), you can reapply immediately after that period with a new assessment. If it was due to an active infection, reapply once recovered. If it was due to an uncontrolled condition, reapply once you have evidence of adequate control. There is no fixed waiting period for reapplication — the relevant factor is whether the clinical concern that caused the refusal has been resolved.
