Finnair's pregnancy rules turn on flight length. Over 2 hours, you may fly to 35 weeks + 6 days; 2 hours or less, to 37 weeks + 6 days; a pregnancy certificate is needed after week 32 only on flights over 6 hours. A doctor on Mobi Doctor can complete the form; video consultations 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.

Finnair has no single cut-off. Check your flight time first: over 2 hours, your last day to fly is 35 weeks + 6 days; 2 hours or less, it is 37 weeks + 6 days; with twins or more it is 31 weeks + 6 days. Paperwork is needed only after week 32 on flights longer than 6 hours: a pregnancy certificate, sent to Finnair at least 72 hours before departure, or a MEDIF if the pregnancy is high-risk.
Finnair applies two thresholds to the scheduled time of each sector on your booking. Two hours decides your last flying day: a short hop is allowed two weeks longer than anything over 2 hours. Six hours decides the paperwork: only a flight longer than 6 hours needs a certificate, and only after week 32. On a connection through Helsinki each sector is judged on its own. The RCOG also notes a higher DVT risk on flights over four hours, worth raising with your doctor.
| Flight length | Last day to fly | Certificate |
|---|---|---|
| 2 hours or less | 37 weeks + 6 days | Not required |
| Over 2 hours, up to 6 hours | 35 weeks + 6 days | Not required |
| Over 6 hours | 35 weeks + 6 days | Required after week 32 |
| Twins or more | 31 weeks + 6 days | MEDIF if high-risk |
Finnair prints the day count beside every limit, so the 36th week ends at 35 weeks + 6 days, the 38th at 37 weeks + 6 days and the 32nd at 31 weeks + 6 days. That is the ordinal count, in which the 36th week runs from 35 weeks + 0 days to 35 weeks + 6 days; anyone assuming week 36 runs to 36 weeks + 6 days would arrive late. Each flight is checked on its own day, the return included. LOT also wants paperwork after week 32 but publishes no maximum week; Norwegian counts back from the due date.
Your treating doctor or midwife signs it. Finnair accepts a certificate signed by a midwife or maternity nurse when it comes from a medical practice in Finland, Sweden, Norway or Denmark. Finnair publishes its own Pregnancy Certificate for Air Travel form and accepts another letter carrying equivalent information. Three statements are essential: whether the pregnancy is singleton or multiple, the expected due date, and that it has progressed without complications. Date it as close to travel as possible and make it cover the entire trip, outbound and inbound, since Finnair sets no fixed validity. Send it through Finnair's contact form at least 72 hours before departure. A high-risk pregnancy needs a MEDIF instead — Part 1 filled in by you, Part 2 by your treating doctor — on the same 72-hour deadline; after bleeding, raised blood pressure or an early-labour scare, ask the doctor which document applies.
Finnair sits in the "letter required from week 32" group of our airline pregnancy rules comparison, but with flight-length conditions that no other carrier in the table attaches. Read the week figures with Finnair's own day counts in mind: the "36" in the table is the last day of the 36th week, 35 weeks + 6 days, not 36 weeks + 6 days. Where it says a certificate is required, that means after week 32 and only if the flight exceeds 6 hours.
| Letter or certificate required from | After week 32, only on flights over 6 hours |
| Last week you can fly, single | Week 36 (35 weeks + 6 days) over 2 hours; week 38 (37 weeks + 6 days) at 2 hours or less |
| Last week, twins or more | Week 32 (31 weeks + 6 days) |
| Letter must be issued within | No fixed limit; dated close to travel, sent 72 hours before departure |
| Own form | Pregnancy Certificate for Air Travel (equivalent letter accepted); MEDIF if high-risk |
| Who can sign | Treating doctor or midwife; Nordic midwife or maternity nurse |

Book on Mobi Doctor and an EU-licensed doctor usually sees you over video within 15 minutes, daily 7am–11pm CET, from anywhere in the EU. The doctor goes through your pregnancy history and, where clinically appropriate, completes Finnair's form or writes a pregnancy fit-to-fly letter with the same three statements, emailed to you after the consultation to send on to Finnair. The price is €54 + €10 for the certificate, and any other question, including a prescription where appropriate, is covered. A doctor's signature also sidesteps the Nordic rule if your midwife practises elsewhere. Wizz Air, at 34 weeks with a 6-day letter, is the opposite extreme.
Only after week 32, and only if the flight lasts more than 6 hours. Shorter flights need no certificate at any stage of an uncomplicated pregnancy; a high-risk pregnancy needs a MEDIF.
It depends on the flight: to 35 weeks + 6 days on flights over 2 hours, and to 37 weeks + 6 days on flights of 2 hours or less. Twins or more: to 31 weeks + 6 days.
Only on a flight of 2 hours or less, where the limit is 37 weeks + 6 days. From 36 weeks + 0 days you are past the 35 weeks + 6 days limit for anything longer.
Yes if she works at a medical practice in Finland, Sweden, Norway or Denmark, where Finnair explicitly accepts a midwife's or maternity nurse's signature. Elsewhere, have a doctor sign it.
Until the end of the 32nd week, 31 weeks + 6 days, if it has progressed normally. Because that limit falls before week 32 ends, the over-6-hours certificate rule never applies to twins.
Finnair sets no maximum age. It asks for a date as close to travel as possible, cover for both outbound and inbound flights, and submission at least 72 hours before departure.
