3. If you are more than 36 weeks pregnant, the airline cannot fly you in principle.
For health and safety reasons:
Generally speaking, pregnant women can fly in the early stages of pregnancy. But after the 28th week of pregnancy, it is better for pregnant women not to fly. This is because when the airplane is at high altitude, there will be a certain pressure difference between the inside and outside of the cabin. For pregnant women more than 28 weeks pregnant, due to more amniotic fluid in the uterus at this time, the uterine tension is high, the pressure difference is easy to cause water breakage and premature labor, and even serious placental abruption, endangering the lives of adults and children. In addition, there is no professional doctor on the airplane, and the medical equipment is far inferior to regular hospitals. In case of premature labor on the plane, it is difficult for pregnant women and babies to get professional care and other accidents are likely to happen. So, you need to avoid overworking as much as you can fly. Pay attention to regular pregnancy tests.
