Norwegian counts from your due date. Until 4 weeks before it you fly with no paperwork; from 4 to 2 weeks before, flights are capped at 4 hours and you carry a fit-to-fly certificate, in English on international routes, valid for the whole trip. A video consultation with a doctor on Mobi Doctor usually starts 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.
Choose a situation to see whether you need documentation.
Nothing applies until you are 4 weeks from your due date. In the final stretch, 4 to 2 weeks before it, Norwegian caps your flight at 4 hours and asks for a medical certificate confirming you are fit to fly, in English on international routes and valid for every flight on the trip. Less than 2 weeks before the due date, Norwegian will not carry you at all.
Norwegian asks only that the certificate confirms you are fit to fly, with three practical conditions. On international flights it must be in English. On a return ticket it must cover the whole period, so the doctor should write both flight dates, or a validity period spanning them. And it stays in your hand luggage at all times, because crew can ask for it after boarding. As the rule hinges on your due date, ask the doctor to state it and to confirm you are not at risk of complications, the two points the NHS says an airline may ask for.
A due date is set at 40 weeks + 0 days. Four weeks before it is therefore 36 weeks + 0 days, and 38 weeks + 0 days is 2 weeks before it. In week terms you need nothing to 35 weeks + 6 days, the certificate and a flight under 4 hours from 36 weeks + 0 days, and "less than 2 weeks" means the day you are exactly 2 weeks out is, on the safe reading, your last possible travel day. Work from the due date on your maternity notes, which is what Norwegian's staff will read.
The 4-hour cap applies per flight, so check the scheduled duration of every sector on your booking. A trip that was fine outbound can be refused on the way back if the return falls inside the window without a certificate, or less than 2 weeks before the due date — so count the return separately and keep the certificate valid until you land. Neighbouring SAS shares the 4-hour and 4-to-2-week structure but demands a MEDIF approved in advance, while Finnair sets its limits by week and flight length.
Norwegian is one of the eight European airlines in our airline pregnancy rules comparison that require no certificate for an uncomplicated pregnancy (in Norwegian's case, until its final weeks), and one of two, with SAS, that frame every rule by due date. Where a row says "not published", Norwegian's page is simply silent on that point: there is no maximum week, no maximum age for the certificate, no twins rule. Confirm those points with Norwegian before booking rather than borrowing another airline's figure.

No. Norwegian's page describes one set of rules and mentions neither twins nor complications. Do not assume the single-pregnancy figures apply: SAS, for instance, moves its whole window forward for multiples, to 12 and 8 weeks before the due date. Ask Norwegian before you book how it treats a multiple pregnancy, then discuss the timing with your midwife or doctor as well, since twins tend to arrive earlier and a due-date rule leaves less margin than a week limit would.
On Mobi Doctor you usually see an EU-licensed doctor over video within 15 minutes; consultations run daily 7am–11pm CET and work wherever you are in the EU. Give the doctor your due date and both flight dates; where clinically appropriate, they issue a pregnancy fit-to-fly certificate in English covering the whole trip, signed and emailed to you after the consultation. The cost is €54 + €10 for the certificate, and it is a complete appointment, so you can ask about anything else too. For the strictest contrast, Wizz Air stops at 34 weeks with a letter under 6 days old; our fit-to-fly certificate page explains the contents.
Only from 4 to 2 weeks before your due date. In that window Norwegian requires a medical certificate confirming you are fit to fly, in English on international flights, kept in your hand luggage throughout.
Norwegian gives no week figure. Taking the due date as 40 weeks + 0 days: unrestricted through 35 weeks + 6 days, short flights with a certificate from 36 weeks + 0 days, not carried once less than 2 weeks remain.
Yes, if your due date is still at least 2 weeks away, the flight is under 4 hours and you carry the certificate. At 37 weeks + 0 days you are 3 weeks before a 40-week due date.
On international flights Norwegian requires the certificate in English. Its page does not say which languages are accepted on domestic flights, so an English version is the safe choice on any route.
Norwegian publishes no separate rule for a multiple pregnancy. Ask the airline before you book and take your midwife's advice on timing, rather than assuming that the single-pregnancy window applies to you.
Norwegian will not carry you on it. Move the return earlier, and check your insurer: the NHS advises making sure a policy covers changing the date of your return trip if you go into labour.
