SAS sets its pregnancy rules by due date, not by week: no certificate until 4 weeks before it, flights under 4 hours with an approved MEDIF from 4 to 2 weeks before, and no flying from 2 weeks before. For the medical part, see a doctor on Mobi Doctor over video, usually 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.
For most of your pregnancy SAS asks for nothing. The restrictions begin 4 weeks before your due date: until 2 weeks before it you may take flights shorter than 4 hours, and only with a MEDIF your doctor has completed and SAS has approved. From 2 weeks before the due date you cannot fly with SAS. With twins or more: MEDIF from 12 weeks before, no flying from 8 weeks before.
A due date sits at 40 weeks + 0 days, so each SAS rule translates into the week counts other airlines use: four weeks before your due date is 36 weeks + 0 days, two weeks before it is 38 weeks + 0 days, and for a multiple pregnancy 12 and 8 weeks before are 28 weeks + 0 days and 32 weeks + 0 days. SAS staff apply the due date on your maternity notes or MEDIF, not a week count you worked out yourself. The boundaries are days: the morning you reach 36 weeks + 0 days the MEDIF rule applies — also where Lufthansa draws its four-weeks-before-the-due-date line.
| SAS wording | Single pregnancy | Twins or more |
|---|---|---|
| No certificate needed | To 35 weeks + 6 days | To 27 weeks + 6 days |
| Flights under 4 hours, approved MEDIF | 36 weeks + 0 days to 37 weeks + 6 days | 28 weeks + 0 days to 31 weeks + 6 days |
| Not permitted to fly | From 38 weeks + 0 days | From 32 weeks + 0 days |
A MEDIF (Medical Information Form) is the standard airline clearance form; SAS uses it for late pregnancy instead of a letter. Your doctor completes and signs it; you upload it through My trips on the SAS website, and SAS emails a confirmation once it has approved it. Two dates govern the timing: the form may not be dated earlier than 1 month before departure, and approval can take up to 7 days, so have it signed between four weeks and one week before you fly. On a codeshare booking check who operates each flight, as partner airlines may apply different rules.
In the restricted window SAS accepts you only on flights under 4 hours; the UK CAA notes that a delivery in flight, or a diversion to an airport without obstetric care, is what airlines want to avoid. Check the scheduled time of every sector on a connecting itinerary, and count the return separately: a return departing less than 2 weeks before your due date is not carried. SAS does not say whether one MEDIF covers both directions — Norwegian, with the same due-date framing, wants one certificate covering the whole trip — so ask SAS if your return is more than a month after the form was signed.
This table sets out the SAS rules in the layout used across our airline pregnancy rules comparison, so you can place SAS beside the week-based carriers. Because SAS gives due-date figures rather than weeks, the conversions in the first table above are ours; SAS's own wording is what its staff will apply. SAS publishes no week-of-pregnancy limit and no separate cut-off week for multiples, so the twins figures on this page are our conversions as well, not an SAS rule.
| Letter or certificate required from | 4 weeks before the due date; multiples 12 weeks before |
| Last week you can fly, single | Not stated by week; to 2 weeks before the due date, flights under 4 hours only |
| Last week, twins or more | Not stated by week; to 8 weeks before the due date |
| Letter must be issued within | 1 month before departure (30 days); approval up to 7 days |
| Own form | MEDIF (uploaded via My trips) |
| Who can sign | Your doctor; SAS approves |

Book a video consultation on Mobi Doctor and you will usually see a doctor within 15 minutes, daily 7am–11pm CET, wherever you are in the EU. The doctor reviews your pregnancy history and due date and, where clinically appropriate, completes and signs the medical section of the SAS MEDIF or issues a pregnancy fit-to-fly letter; the signed document is emailed to you after the consultation. It costs €54 + €10 for the certificate, and as it is a full consultation you can raise anything else, including a prescription where appropriate. Finnair is the Nordic carrier to compare for week-based rules.
Not until 4 weeks before your due date. From then until 2 weeks before it, yes: a MEDIF completed and signed by your doctor, uploaded through My trips and approved by SAS.
SAS does not answer by week. Converted from a 40-week due date: unrestricted to 35 weeks + 6 days, short flights with an approved MEDIF from 36 weeks + 0 days, no flying from 38 weeks + 0 days.
Yes, if the flight is under 4 hours and SAS has approved your MEDIF. At 36 weeks + 0 days you are exactly 4 weeks before a due date set at 40 weeks.
No. At 38 weeks + 0 days you are 2 weeks before your due date, and SAS says you are not permitted to fly from that point, whatever your certificate says.
Yes, until 8 weeks before your due date. Between 12 and 8 weeks before it (28 weeks + 0 days to 31 weeks + 6 days) you need an approved MEDIF and a flight under 4 hours.
It may not be dated earlier than 1 month before departure. Because approval can take up to 7 days, have it signed and uploaded more than a week before you fly, inside that window.
