When do I need a fit-to-fly letter?
Most airlines ask for one from around 28 weeks, and most refuse travel after 36 weeks for a single pregnancy or 32 weeks for twins or more.
Cut-offs are the airline's, not ours, and they vary. Check your specific airline before booking either the flight or this appointment.
Can you override the airline's cut-off?
No. No doctor can. If you are past their limit, a letter saying you are well does not change their policy — it is a commercial and operational rule about a plane being hours from a hospital.
Ask the airline about changing your dates instead; many will waive a change fee on medical grounds.
Can you tell me my due date?
No — we report it, we do not establish it. Your EDD comes from your booking scan, and we do not perform scans.
Bring your maternity notes or app. Without them we cannot confirm gestation, and a letter that guesses is worthless to an airline.
Is it safe to fly while pregnant?
For an uncomplicated pregnancy, flying is generally considered safe, and the RCOG says so. The second trimester is usually the most comfortable.
The considerations are practical rather than dramatic: clot risk is raised in pregnancy and further on flights over about four hours, and the real question is what happens if labour or a complication starts somewhere without the care you would want.
Do I need compression stockings?
Often worth it on longer flights, and more so with additional risk factors — a previous clot, raised BMI, a multiple pregnancy. Properly fitted ones, not fashion socks.
Alongside that: aisle seat, move hourly, drink water, and avoid sitting completely still for hours.
How close to my flight should the letter be dated?
Usually within seven days of departure, and check whether the return leg needs covering too. Read your airline's wording and time the appointment to it — an early letter is a wasted fee.
What if I have complications?
Then this is not the right appointment, and we will say so rather than write the letter.
Bleeding, reduced fetal movements, raised blood pressure, placenta praevia, a previous preterm birth, or a complicated multiple pregnancy all need the answer to come from your midwife or obstetrician, who have your full picture.
If you have had bleeding or reduced movements at any point, contact your maternity unit today — that is urgent and quite separate from travel.
What about Zika, malaria and vaccinations?
Destination matters more in pregnancy than most people expect, and it is worth discussing at the appointment. Zika is a genuine reason to reconsider a destination; antimalarial choice varies by trimester, and some are not suitable at all.
We can advise and refer, though we do not administer travel vaccinations — those need a travel clinic.
Will my travel insurance cover me?
Check the policy wording rather than assuming. Many exclude pregnancy beyond a certain gestation, and many exclude neonatal care entirely — which is the expensive part if a baby arrives early abroad.
A fit-to-fly letter is not insurance and does not make you insured. Some insurers ask to see one; none accept it in place of cover.
Do I need one for the return journey?
Often yes, and it is the half people forget. Your gestation on the return date is what matters, and some airlines apply the cut-off to the last flight rather than the first. We state both dates in the letter.
