LET'S GET STARTED Pregnancy Fitness to Fly – Medical Review Criteria
When a Pregnancy Fit-to-Fly Certificate May Be Appropriate
A pregnancy fit-to-fly certificate provides medical confirmation that, based on the information supplied, there is no identified clinical reason preventing air travel at the time of assessment. Airlines may request documentation during later stages of pregnancy or where specific medical factors are present.
For general NHS guidance on pregnancy health and travel considerations, see travelling in pregnancy and signs of labour.
Clinical Criteria — What Is Considered
During review, a clinician considers gestational age, symptom stability, and any pregnancy-related complications.
- Gestational stage and airline policy requirements.
- Absence of pregnancy complications such as uncontrolled bleeding, severe pre-eclampsia symptoms, or threatened preterm labour.
- Stable maternal health without symptoms that could reasonably worsen during travel.
- No current medical restriction advising against air travel.
When a Certificate May Not Be Issued
To ensure maternal safety, a certificate will not be issued where:
- There are signs of imminent labour or pregnancy complications.
- There are concerning symptoms requiring in-person assessment.
- Insufficient clinical information is provided to assess safety.
- The requested statement exceeds what can be medically supported.
How the Review Works
- Pregnancy information review – gestational age, symptoms, and relevant medical history are evaluated.
- Risk consideration – potential in-flight factors (immobility, cabin pressure, timing of travel) are considered.
- Certification (if appropriate) – a signed certificate is issued confirming medical assessment at that time.
Clinical Accountability
All pregnancy fit-to-fly requests are reviewed by a GMC-registered doctor. Certificates are issued only when air travel appears medically reasonable at the time of review.
Please note: Airlines apply their own gestational cut-offs and documentation requirements. A certificate provides medical confirmation but does not override airline policy or guarantee boarding.

Asked Questions
Who needs a pregnancy fit-to-fly certificate?
Most airlines require pregnant women travelling beyond 28 weeks to have medical clearance to fly. This is usually in the form of a medical certificate or letter from a doctor. We can help! No appointment required, and no need to visit a doctor. Simply complete our online request form now.
How do I get an urgent fit-to-fly letter or certificate?
It’s quick and easy! Simply complete the brief online questionnaire and complete the payment. After purchasing your fit-to-fly letter online, a doctor will review the medical evidence the same day and we will provide you with your unique fit-to-fly certificate for you to present to your airline. There is no need to have a telemedicine or online consultation to receive a fit-to-fly certificate. Our Doctors may call or email you directly if they have any additional questions.
Can I get a fit-to-fly letter without seeing a doctor?
You do not need to see a GP to get one. Our revolutionary online service allows you to be assessed by one of our GPs without needing an appointment, simply by uploading your details and evidence through our forms. One of our GPs will then consider your medical history, symptoms, and any potential risks associated with your condition and travel before issuing your medical certificate. You will then receive the letter directly to your inbox.
What medical evidence will you require?
We will require you to upload:
✓ A photo / copy of your Passport to confirm your identity
✓ Complete a short medical questionnaire
✓ A copy/pictures of your antenatal (pregnancy) clinical notes.
Do you provide refunds?
We always provide full refunds if we are unable to provide a Medical Letter in your situation, so you can submit your requests with peace of mind. Once a fit-to-fly has been issued we are unable to offer refunds.

Our team of GPs will review your medical evidence and questionnaire on the same day and provide you with your medical letter or certificate within 1 working day.

Who will sign my fit-to-fly Letters and medical certificates?
All of the doctors at Medical Cert are fully licensed GMC-registered GPs, unlike many other services who use very junior non-specialist doctors, which may sometimes cause their letters to be rejected.

We are a UK based healthcare service but the certificates can be used for airlines internationally. All of our Doctors are registered GPs with the UK General Medical Council.
How far in Advance should I request my fit-to-fly letter?
Generally, the earlier you apply for a fit-to-fly the better. However it is essential to check with your particular airline for their specific requirements, as some airlines may require the letter to be completed within 6 days of the booked flight, while others allow several weeks. Our service is quick and subject to clinical assessment within the advertised time-frame, so you can plan your travel with peace of mind.
Can you complete a specific form required by airline?
Yes, in most cases we can help with special forms required by airlines. Simply upload the required form together with your medical evidence. There is a £10 fee for an add-on certificate, which will be issued in addition to our standard fit to fly certificate.
Can your doctor’s letters be verified by the airline?
Absolutely. Each letter or certificate issued will have a unique reference number and can be verified free of charge by emailing us at verify@medicalcert.co.uk.
Do I need a fit-to-fly for domestic flights?
Each airline issues their own policy which we encourage you to refer to, however most airlines do require a fit-to-fly for pregnant women regardless of the destination or length of flight.

Yes, fit-for-flight letters issued by Medical Cert UK are widely accepted by airlines internationally.

Risks & Considerations for Flying During Pregnancy
Flying is generally considered safe for women with uncomplicated pregnancies. The following factors are worth discussing with your midwife or GP before travel.
First Trimester
Nausea and fatigue can make flying uncomfortable. The risk of miscarriage is relatively higher in this period, though flying does not increase this risk for most women.
Second Trimester
Many women find the second trimester the most comfortable period for travel. Symptoms tend to ease and the fit to fly certificate requirement does not yet apply for most airlines.
Third Trimester
Airlines begin requiring a certificate from 28 weeks. As pregnancy progresses, discuss the timing and appropriateness of travel with your midwife or consultant.
Blood Clot Risk & DVT
Pregnant women face an elevated risk of deep vein thrombosis (DVT) on long flights. Wearing compression stockings, moving regularly, and staying hydrated can help reduce this risk.
Alternatives to Flying During Pregnancy
If air travel is not clinically advisable or you prefer not to fly, several alternatives may suit your needs.
Train — Comfortable, spacious, and allowing frequent movement. Often a practical option for UK or European travel.
Ferry — A leisurely pace with fresh air, though sea sickness may be a consideration for some pregnancies.
Private car — Offers flexibility and control over rest stops, making it suitable for shorter distances.
Staycation — Eliminates long-distance travel concerns entirely and may be the most suitable option in late pregnancy.
Flying remains safe for most women with uncomplicated pregnancies. These alternatives are worth considering if your GP or midwife advises against air travel, or if you are beyond the gestational limits accepted by airlines.
