During a healthy pregnancy, it’s generally safe to fly until 36 weeks. Most airlines in the United States allow pregnant women to fly domestically in their third trimester before the 36th week. Some international flights restrict travel after 28 weeks.
Airport X-rays and advanced imaging technology are generally considered safe for all passengers, including pregnant women.
If you’re concerned, you request a pat-down screening instead of walking through a metal detector. Tell the officer at airport security you’re pregnant and are opting for a pat-down. A female security officer will inform you of the process and perform the screening.
