Austrian Airlines carries an uncomplicated single pregnancy without a certificate up to the start of the 36th week — six days earlier than the end-of-week-36 rule most airlines use — or four weeks before the due date; twins to the end of week 32. For the recommended certificate, video appointments with a doctor on Mobi Doctor usually start 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.

No certificate is required, but the clock stops earlier than you may expect. Austrian's limit is the start of the 36th week — in practice, your last flights fall in week 35 — or four weeks before your due date. Twins or more: to the end of week 32. After week 28 Austrian recommends a certificate confirming the pregnancy is progressing straightforwardly, does not prevent flying and stating your due date. A risk pregnancy is not carried.
Six days. Most airlines let you fly "to the end of week 36", which runs to 36 weeks + 6 days. Austrian's wording is "the start of the 36th week", and its own alternative phrasing, four weeks before the expected date of delivery, pins that to 36 weeks + 0 days. So the safe plan with Austrian is to have flown by 35 weeks + 6 days. It applies to the date of each flight, return included. SWISS writes "the end of the 36th week", and easyJet stops at the end of week 35, which in practice is the same boundary.
If your pregnancy has been classed as high-risk, Austrian's position is that you should not fly at any week, and no certificate changes that. Austrian does not define the term, so the judgement sits with your gynaecologist or treating physician. The RCOG lists situations where flying may not be advised, among them an increased risk of preterm labour, severe anaemia, a recent sickle cell crisis, recent significant vaginal bleeding and serious heart or lung conditions. If any of those applies, talk to your doctor before booking; a doctor on Mobi Doctor can discuss it over video, though a letter is issued only where clinically appropriate.
After the 28th week. Austrian calls it a gynaecological certificate and wants it to confirm that the pregnancy is progressing straightforwardly and does not prevent you from flying, and to include the expected due date. It sets no maximum age for the document and has no form of its own, so a dated doctor's letter does the job; date it as close to travel as you can, and have it cover both directions if you are flying back inside the recommendation window. Any licensed doctor can sign; no airline requires a UK GP.
Austrian is one of the four airlines that only recommend a certificate in our airline pregnancy rules comparison, alongside Lufthansa, SWISS and Eurowings — but it is the only one of the four whose single-pregnancy limit is week 35 rather than week 36, and the only one to state that a risk pregnancy is not carried. The rows below use the convention that "week 32" means to the end of that week, 32 weeks + 6 days, while the single-pregnancy row carries Austrian's own wording so that the day boundary stays visible.
| Letter or certificate required from | Not required; recommended after week 28 |
| Last week you can fly, single | Week 35 — to "the start of the 36th week" (36 weeks + 0 days), or four weeks before the due date |
| Last week, twins or more | Week 32 (to 32 weeks + 6 days), uncomplicated only |
| Letter must be issued within | Not published |
| Own form | None |

Austrian's page goes further than most on in-flight precautions against deep vein thrombosis. It suggests drinking an additional one to two litres on flights of over three to four hours, wearing loose, comfortable clothing, and using compression stockings of compression class 1 to 2, fitted with expert advice. It also asks you to discuss any flight during pregnancy with your gynaecologist or treating physician beforehand. None of it is a boarding condition, but it is worth raising when you see the doctor about your certificate, particularly before a long sector.
Pick a slot on Mobi Doctor and an EU-licensed doctor will usually join you over video within 15 minutes, daily 7am–11pm CET, wherever you are in the EU. Tell the doctor your due date, whether it is a single or multiple pregnancy and your flight dates; where clinically appropriate, the doctor issues a pregnancy fit-to-fly letter with the wording Austrian asks for, and it is emailed to you after the consultation. The fee is €54 + €10 for the certificate, covering a complete consultation — so a prescription where appropriate costs nothing extra.
Not for an uncomplicated pregnancy. Austrian recommends a gynaecological certificate after week 28, confirming the pregnancy is progressing straightforwardly, does not prevent flying and giving the due date. Carry it anyway.
Up to the start of the 36th week, or four weeks before your due date, with one baby — in practice, week 35. With twins or more, to the end of week 32 if uncomplicated.
Do not plan on it. Austrian's limit is the start of week 36, so 36 weeks + 0 days is the very edge of the rule and anything later in the week is outside it. Fly in week 35 instead.
Yes, until the end of the 32nd week, as long as the multiple pregnancy is uncomplicated. Austrian classes a risk pregnancy as a contraindication to flying, so complications with twins mean no flight, whatever the week.
Austrian sets no maximum age. Since the letter exists to show your due date and that the pregnancy is progressing normally, have it dated close to departure and valid for the return.
Austrian applies its limit to each flight, so a return at or after the start of week 36 (or inside the four weeks before your due date) is refused; move the return earlier.
