Transavia lets you fly until 36 weeks with no medical certificate, provided your pregnancy has been uncomplicated. Expecting more than one baby, or had complications? Then the cut-off is week 34, and complications mean a certificate is required. A doctor on Mobi Doctor can assess you over video, usually within 15 minutes.
Or plan by dates. Enter your due date and flight dates: the planner works out how pregnant you will be on each flight, whether that flight is allowed, whether a letter is needed for each leg, and the dates a letter must be signed between so it is still valid on the way home.
Copy the flight lines from the airline’s confirmation email (flight number, date, times) and paste them here. It is read in your browser; nothing is sent anywhere.
Enter your flight number and the dates above (or a route), and the planner fills in the airline — the operating carrier on a codeshare — and the flight time from the published schedule.
Or by route: to on the outbound date.
Choose a situation to see whether you need documentation.
For most pregnant passengers Transavia asks for nothing: no letter, no form, no advance notice, until 36 weeks. Two situations change that. If you are expecting twins or more, the last week you can fly is week 34. If there have been complications, the same week-34 limit applies and you must carry a medical certificate confirming that you are fit to fly.
Only passengers whose pregnancy has had complications. Transavia's page makes the certificate conditional on complications, not on the week you have reached, which sets it apart from the 18 airlines in our comparison that demand a letter from a fixed week. An uncomplicated twin pregnancy is not asked for a certificate either; it simply stops flying earlier, at week 34.
That makes Transavia one of eight airlines needing no letter for a normal pregnancy, alongside KLM and easyJet. The full picture is on our airline pregnancy rules page.
Transavia does not define the term, so read it broadly. Anything that has needed extra monitoring or treatment, whether bleeding, raised blood pressure, a placenta concern or a threatened early labour, is the kind of history crew could reasonably ask about.
The NHS advises talking through any complication with your midwife or doctor before flying, and a certificate is the written outcome of that conversation. If in doubt, get one: it costs less than a refused boarding, and the doctor may spot something that should change your plans.

Only Wizz Air stops a single pregnancy as early as Transavia stops twins, at 34 weeks, and it wants a letter issued within 6 days.
Transavia says you can fly "until 36 weeks" and that after 36 weeks you may no longer fly; we record week 36 as the last week for a single pregnancy. Work in completed weeks plus days for each flight's date: a return at 36 weeks + 2 days sits inside week 36. If a flight falls inside that final week, confirm the date with Transavia, because "until 36 weeks" can be read either way.
For twins or a pregnancy with complications the page says you may not fly after your 34th week, so the last day is 34 weeks + 6 days. Our flying while pregnant guide explains the counting.
Transavia sets no content, no format and no validity period, so write for the strictest reader. A useful certificate states your due date, whether one baby or more is expected, your weeks on each flight date, what the complication was and that it is resolved or stable, and that you are fit to fly, signed and dated by the doctor with their registration number.
Write it in English, date it close to departure and name both flights so one document covers the trip. The fit-to-fly certificate page shows what a letter issued through Mobi Doctor contains.
Doctors on Mobi Doctor are available daily 7am–11pm CET; pick a slot and a doctor talks to you over video, usually within 15 minutes. Bring your maternity notes and any hospital letters about the complication, because the doctor will ask what happened, when, and how it was managed.
Where clinically appropriate, the doctor issues the certificate and you receive it by email after the consultation. Fee: €54 + €10 for the certificate, with anything else you want to ask covered in the same appointment. If the doctor concludes you should not fly, you get advice and, if needed, a letter for your insurer instead.
Only if there have been complications in your pregnancy. An uncomplicated pregnancy, single or multiple, flies without a certificate, up to 36 weeks (34 for twins or more). After complications, carry a doctor's certificate confirming you are fit to fly.
Until 36 weeks for a single, uncomplicated pregnancy. If you are expecting a multiple birth, or there have been complications, you may not fly after your 34th week. Count your week on each flight date, including the return.
Transavia's wording is "until 36 weeks", and it says that after 36 weeks you may no longer fly. If your flight falls inside week 36 rather than before it, confirm the exact date with Transavia; at 37 weeks the answer is no.
No. A multiple pregnancy may not fly with Transavia after the 34th week, so the last possible day is 34 weeks + 6 days. Book the return before then; a certificate does not extend the limit for twins.
Transavia sets no maximum age. Date it as near to departure as is practical and make sure it names both flight dates and your week on each, so one certificate covers the whole trip.
No. Transavia names no form, template or validity period. Unlike Ryanair, whose own form must be shown to cabin crew from week 28, a plain doctor's certificate is enough where Transavia asks for one.
A return after 36 weeks (34 with twins or after complications) is a flight Transavia says you may not take, so change it before you travel. KLM, often on the same routes, is stricter, with last flights in week 35.
