Air France needs no medical clearance from pregnant passengers at any stage. It asks two things instead: seek your doctor's opinion before you travel, and avoid flying from week 37 or within 7 days of giving birth. This page turns that advice into dates, covers the missing twins rule, and explains what a doctor's opinion looks like on paper.
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.
No fit-to-fly certificate and no medical clearance is needed to fly with Air France. The airline recommends getting your doctor's opinion before travelling and asks you to avoid flying from week 37, which makes 36 weeks + 6 days your last Air France day, and to avoid flying in the 7 days after childbirth. There is no published twins limit, so for a multiple pregnancy the doctor's opinion is the only rule you have.
Air France's phrasing is deliberately light: it recommends you seek your doctor's opinion before travelling, and never says it must be written down or shown. It means a consultation: a doctor or midwife checks your dates, whether the pregnancy has been straightforward and whether anything argues against flying. The useful output is a dated letter recording that assessment, with your due date and fitness to fly; Air France does not need it, but a border officer, a stricter connecting airline or an insurer may.
Wherever you are in the EU, that opinion is available by video from a doctor on Mobi Doctor, usually within 15 minutes; where clinically appropriate the signed fit-to-fly certificate (€54 + €10 for the certificate) follows by email.
The instruction is to avoid travel from week 37. Week 37 starts at 37 weeks + 0 days, so your last Air France day is 36 weeks + 6 days: a week later than KLM, easyJet or Vueling, whose boundary sits at 35 weeks + 6 days.
Apply the count to each flight. An outbound at 35 weeks + 5 days with a return eight days later brings you home at 36 weeks + 6 days, still inside the advice; a nine-day trip would not be. After the birth, wait the 7 days Air France asks for.

No. Air France's page has no line on multiple pregnancies and no form; everything rests on the doctor's opinion and the week-37 point. That leaves a gap, because airlines that do publish a twins figure set it well before week 37 (week 32 at Lufthansa and British Airways, week 31 at Iberia and Vueling); the RCOG puts the sensible stop for uncomplicated twins at 32 weeks.
Do not borrow the single-pregnancy date: ask Air France, and make the doctor's opinion a real assessment. If the doctor advises against the trip, a not-fit-to-fly certificate backs up the insurance claim.
Air France's page says more about comfort than rules, and the advice is sound: seat belt below the abdomen, low on the pelvis; compression stockings; an aisle seat and a walk from time to time; frequent drinks, none carbonated, and no heavy meals; comfortable layers. On flights of 2.5 hours or more you can pre-order a special meal (low-sodium, low-sugar or vegetarian).
The NHS adds that travel over 4 hours carries a small extra clot risk, which is why the stockings and walking matter; graduated stockings must be correctly sized, so ask the doctor.
KLM, Air France's group partner, is a week stricter, advising a stop at 36 weeks (last week 35); it too wants nothing in writing and has no twins limit. Lufthansa shares the end-of-week-36 boundary but recommends a gynaecologist's certificate from week 28 and caps twins at 32. Vueling differs sharply: an original medical authorisation with validity dates and the doctor's medical board number for weeks 28 to 35, and no carriage from week 36. Each leg follows its operating airline's rule; the airline pregnancy rules hub sets all 30 side by side.
No. Air France requires no medical clearance at any stage. It recommends your doctor's opinion before travelling; a letter recording it helps with borders, connecting airlines and insurers, but Air France will not ask for one.
Air France asks you to avoid travel from week 37, so on departure day you can be 36 weeks + 6 days at most. Count each flight separately; the return must land before then.
Air France asks you not to. At 37 weeks + 0 days the period the airline says to avoid has begun, and no letter changes that. Rebook into week 36 or earlier.
Air France publishes no limit for a multiple pregnancy. Do not assume the week-37 point applies: carriers that state a twins figure use 31 or 32 weeks, as does the RCOG. Ask Air France and your doctor.
Air France asks you to avoid flying during the 7 days following childbirth. After that it is a medical decision for you and your doctor, and a separate booking question for the baby.
Your due date, that the pregnancy is uncomplicated and that you are fit to fly on both flight dates, signed by a licensed doctor or midwife; see the pregnancy fit-to-fly guide for what to include.
