Brussels Airlines states its rule two ways: one page "recommends" a medical clearance beyond week 28, its FAQ says you "must" have one. Follow the stricter. Fly up to 36 weeks or four weeks before your due date; the clearance goes to the Medical Assistance Service Team within 72 hours of departure. A doctor on Mobi Doctor can complete it.
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.
Plan on a medical clearance from week 28. Brussels Airlines calls it a recommendation in one place and a requirement in another, and warns that without documents proving your due date you may be denied boarding, so read it strictly. Have a doctor complete the clearance form, send it to the Medical Assistance Service Team within 72 hours of departure, and fly no later than 36 weeks or four weeks before your due date.
The pregnancy page says a medical clearance is recommended beyond the 28th week; the FAQ says you must have one to fly beyond the 28th week. When an airline contradicts itself, staff decide on the day, and the version that can cost you a flight is the strict one. So treat the clearance as mandatory from 28 weeks + 0 days. That sets it apart from its Lufthansa Group siblings: Lufthansa and Eurowings only recommend a certificate from week 28 and require nothing for an uncomplicated pregnancy.
Three statements: that the pregnancy is progressing without complications, the expected due date, and that the pregnancy does not prevent you from flying. Brussels Airlines provides its own medical clearance certificate for a doctor to complete, and a separate form for a multiple pregnancy. It sets no maximum age, so date it close to departure and have it cover the return. Double-check the due date: the airline's denied-boarding warning is specifically about proving it. The UK CAA lists the same three elements as what most airlines want after 28 weeks.
Brussels Airlines asks for the documents to reach its Medical Assistance Service Team within 72 hours of departure — read that as no later than 72 hours before you fly, and earlier if you can. The team works office hours: Monday to Friday 9:00–16:00, and 9:00–13:00 on Saturdays, Sundays and bank holidays, on +32 2 723 8014. A form sent late on a Friday afternoon may therefore not be seen before Monday. Keep a printed copy with your passport as well.
Brussels Airlines is one of the twelve carriers wanting paperwork from week 28 in our airline pregnancy rules comparison, even though one of its pages softens that to a recommendation. Its limit is phrased as "36 weeks into their pregnancy", which is 36 weeks + 0 days, and as four weeks before the due date, which falls on that day too; do not read it as the end of week 36. The twins row is empty because the airline is silent, not because the single limit applies.
| Letter or certificate required from | Beyond week 28 (FAQ: must; pregnancy page: recommended) |
| Last week you can fly, single | Week 36 — "up to 36 weeks", i.e. 36 weeks + 0 days, or 4 weeks before the due date |
| Last week, twins or more | Not published — ask the airline |
| Letter must be issued within | Not published; sent within 72 hours of departure |
| Own form | Medical clearance certificate; separate form for a multiple pregnancy |
| Who can sign | A doctor |

Up to 36 weeks, or four weeks before the expected due date, provided you are in normal health; both point to 36 weeks + 0 days, so plan your last flight for week 35. Count the return separately: a return at 36 weeks + 1 day is refused whatever the outbound date. For twins or more, Brussels Airlines publishes no week limit at all; it offers a dedicated multiple-pregnancy clearance form, so ask the Medical Assistance Service Team before booking rather than assuming the week-32 figure used by TAP or Lufthansa.
A video consultation on Mobi Doctor usually puts you in front of an EU-licensed doctor within 15 minutes, daily 7am–11pm CET, wherever you are in the EU, useful when the 72-hour deadline is close. The doctor reviews your history and, where clinically appropriate, completes the form or issues a pregnancy fit-to-fly letter carrying those three statements, signed, then emailed to you after the consultation to forward to the team. The price is €54 + €10 for the certificate; the appointment is a full one, so other advice, or a prescription where appropriate, is included.
Yes, beyond week 28 — Brussels Airlines' FAQ says you must have a medical clearance, although its pregnancy page calls it recommended. It must confirm no complications, give the due date and say you may fly.
Up to 36 weeks into the pregnancy, or four weeks before the expected due date, if you are in normal health. Both descriptions land on 36 weeks + 0 days, so treat week 35 as your last week.
At 36 weeks + 0 days you are on the boundary the airline sets; later in week 36 you are past it. Book for week 35 or earlier, with the clearance already sent.
Brussels Airlines has a separate medical clearance form for a multiple pregnancy but publishes no week limit for twins. Complete that form with your doctor and ask the Medical Assistance Service Team how late you can travel.
No maximum age is published. The airline's timing rule is about submission — within 72 hours of departure — so have it completed shortly before you send it, and make sure it covers both flights.
Not during the 7 days following birth. After that, Brussels Airlines asks you to contact its Service Centre with the baby's exact date of birth and full name to complete the booking.
General information, not medical advice — always confirm with your airline before you travel.
