Lufthansa carries an uncomplicated pregnancy to the end of week 36 (twins to week 32) without paperwork, but from week 28 it recommends an up-to-date gynaecologist's certificate and publishes its own form. Here is what the form asks, why "recommended" deserves respect, and how a doctor on Mobi Doctor helps.
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.
You do not need a fit-to-fly letter for Lufthansa if your pregnancy has been uncomplicated: the airline flies you until the end of week 36, twins until week 32, without a certificate. From week 28, however, Lufthansa recommends an up-to-date gynaecologist's certificate and provides a form for it, so most third-trimester passengers carry one. After complications the allowance ends.
At Ryanair or British Airways a letter from week 28 is a condition of carriage; at Lufthansa it is advice, and nothing on the page says a passenger at 30 weeks without one is refused.
Still carry it. The no-certificate allowance covers pregnancies that have progressed without complications; if yours has not, a doctor's letter shows you are nonetheless fit to fly. A document stating your due date settles any question at the gate, and Lufthansa warns that some countries impose stricter limits, so border staff may want paper.
Lufthansa provides a downloadable certificate for your gynaecologist to complete. It is optional (a letter with the same content works) but it shows what the airline wants:
The UK CAA says most airlines want the same three things after 28 weeks. Lufthansa sets no age limit, only "up-to-date": date it shortly before departure, with your due date stated so it still reads correctly on the return. The pregnancy fit-to-fly guide explains what goes in the letter.
Lufthansa states the limit two ways: until the end of the 36th week, or until the date four weeks before your expected delivery. The end of week 36 means 36 weeks + 6 days; 37 weeks + 0 days is outside it. Four weeks before a due date fixed at 40 weeks + 0 days is 36 weeks + 0 days, up to six days earlier, so plan to the earlier date.
Twins or more, uncomplicated: the end of week 32, meaning 32 weeks + 6 days. Every flight counts on its own date.
| Letter or certificate required from | Not required; recommended beyond week 28 |
| Last week you can fly, single | Week 36 (36 weeks + 6 days), or four weeks ahead of the due date |
| Last week, twins or more | Week 32 (32 weeks + 6 days), uncomplicated |
| Letter must be issued within | No limit published; "up-to-date" is the only wording |
| Own form | Yes: "Pregnancy Statement for Air Travel" |
| Who can sign | A gynaecologist, per Lufthansa; being advisory, any licensed doctor who has reviewed the pregnancy can provide it |
| Source checked | lufthansa.com, "Travelling healthy", 24 September 2026 |
Multiples: the end of week 32 is the limit and the week-28 recommendation applies equally, so the letter window is barely four weeks wide.
Complications are the dividing line. Lufthansa's page has no separate rule for a pregnancy that has not run smoothly; it expects you to consult your gynaecologist, and the certificate becomes evidence that you were cleared. If the doctor says no, a not-fit-to-fly certificate supports the insurance claim. If a scan moves your due date, recount: the four-weeks-before cap follows the date in your notes.
Your gynaecologist or midwife can complete Lufthansa's form at any appointment. If there is none before you fly, or the return needs a fresh statement, book a video consultation on Mobi Doctor: a doctor is with you on video usually within 15 minutes, wherever you are in the EU; the service runs daily 7am–11pm CET. The doctor reviews your dates and, where clinically appropriate, signs a pregnancy fit-to-fly certificate covering Lufthansa's three points, emailed after the consultation. The charge is €54 + €10 for the certificate; ask about anything else in the same appointment. No airline requires a UK GP, not even the British ones.
Lufthansa Group airlines look alike but do not match. SWISS mirrors Lufthansa on every figure: certificate recommended from week 28, end of week 36, twins to week 32. Eurowings also allows flying to the end of week 36 and recommends a certificate from week 28, but publishes no rule for a multiple pregnancy. Austrian Airlines is the one to watch: it stops at the start of week 36, making week 35 your last Austrian flight. All 30 carriers are compared on the airline pregnancy rules hub.
Not for an uncomplicated pregnancy: Lufthansa takes you to the end of week 36 without one. From week 28 it recommends an up-to-date certificate and publishes a form for your gynaecologist.
Until 36 weeks + 6 days with one baby (the end of week 36) or, if earlier, four weeks before your due date; until 32 weeks + 6 days if carrying twins or more.
Yes, if you are no more than 36 weeks + 6 days when the flight departs and your due date is at least four weeks away. One day later and Lufthansa's allowance has ended.
It asks the gynaecologist to confirm the pregnancy is progressing without complications, give the expected due date and state expressly that the pregnancy does not prevent flying. A letter with those points serves equally well.
An uncomplicated twin or multiple pregnancy is carried to the end of week 32 (32 weeks + 6 days). Lufthansa recommends a certificate from week 28 for multiples too, so arrange it early.
Every flight is judged separately, so a return at 37 weeks + 0 days is not permitted. Leave at 35 weeks + 4 days and a nine-day trip lands you home on the last permitted day.
