The general consensus on flying during pregnancy is as follows:
- For a single pregnancy, it is considered safe to fly up to about 36-37 weeks of pregnancy. Most airlines do not allow pregnant women to fly after 36 or 37 weeks due to the increased risk of labor and complications
- For twin or multiple pregnancies, the safe flying period is shorter, usually up to around 32 weeks
- After 28 weeks, many airlines require a medical certificate or letter from a doctor or midwife confirming the pregnancy is progressing normally and stating the due date. This is to ensure the traveler is not at risk of complications during the flight
- Some airlines have specific rules based on flight duration. For example, Finnair allows flying until the end of the 36th week for flights over 2 hours, and up to 38 weeks for flights 2 hours or less, but requires medical certificates after 32 weeks for long flights
- The safest time to travel by air is generally the second trimester (14 to 28 weeks), when the risk of miscarriage and preterm labor is lowest and pregnancy symptoms are often milder
In summary, you can typically fly safely up to about 36-37 weeks if you have a single pregnancy without complications, and up to about 32 weeks if you are carrying twins or multiples. Always consult your healthcare provider before flying, especially in the later stages of pregnancy, and check the specific airline's policies.
Key points:
- Single pregnancy: fly safely up to ~36-37 weeks
- Multiple pregnancy: fly safely up to ~32 weeks
- Medical certificate often required after 28 weeks
- Best time to fly: second trimester (14-28 weeks)
- Check airline rules and consult your doctor before booking
