Generally, air travel before 36 weeks of pregnancy is considered safe for people who aren't dealing with any pregnancy problems. Still, if you're pregnant, it's a good idea to talk with your health care provider before you fly.

Yes, for most women with an uncomplicated pregnancy, flying at three months (the end of the first trimester) is considered completely safe by organizations like the American College of Obstetricians and Gynecologists (ACOG). By the third month, the initial morning sickness often begins to subside, and you are not yet so large that physical discomfort becomes a major issue. However, you should be aware of the increased risk of Deep Vein Thrombosis (DVT), as pregnancy naturally increases blood clotting factors. To mitigate this, it is recommended to wear compression socks, drink plenty of water, and walk the aisle every hour to keep circulation moving. While the "cabin pressure" and cosmic radiation at 35,000 feet are negligible for a healthy pregnancy, you should always consult your doctor before a long-haul flight to ensure there are no specific medical reasons to avoid travel. It is also a "pro-tip" to carry a copy of your prenatal records and locate the nearest hospital at your destination, just for peace of mind during your "babymoon."
