For healthy pregnant women, occasional air travel is almost always safe. Most airlines allow pregnant women to fly domestically until about 36 weeks of pregnancy. Your ob-gyn or other health care professional can provide proof of your due date if you need it.
Can you fly in the first 12 weeks of pregnancy?
Some women prefer not to travel in the first 12 weeks of pregnancy because of nausea and vomiting and feeling very tired during these early stages. The risk of miscarriage is also higher in the first 3 months, whether you're travelling or not. Travelling in the final months of pregnancy can be tiring and uncomfortable.
Is it a risk to fly when pregnant?
Generally, commercial air travel before week 36 of pregnancy is considered safe if you have a healthy pregnancy. Still, if you're pregnant, check with your health care provider before you fly.
