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.Your health care provider might caution against air travel if you’re experiencing pregnancy complications that might be worsened by air travel or require emergency care. The duration of the flight also should be considered. Similarly, your health care provider and many airlines might restrict travel after 36 weeks of pregnancy. If your health care provider approves air travel and your plans are flexible, the best time to fly might be during your second trimester. This is when the risks of common pregnancy emergencies are the lowest.
