Typically, pregnant women are not allowed to travel by air after 36 weeks within domestic routes. At the same time, they cannot fly after 28 to 35 weeks on international flights. Most airlines also impose certain regulations on the travel of pregnant ladies. Moreover, the decision of whether a pregnant lady should take flights depends on various factors. The best time to travel is mid-pregnancy, within 14 to 28 weeks. Therefore, you must make your travel plans when safe for you and your baby. After 28 weeks, it becomes hard to move around or even sit in the same position for a long time.
