Well wishers may tell you that travelling by air is not safe during pregnancy. This is only partly true. Passing through airport security or flying by airplane is completely safe during pregnancy.
If you’re doubtful, inform the person at the airline counter about your pregnancy and they will guide you appropriately. However, if you’re a frequent flyer, you need to exercise caution as factors such as radiation, dehydration and air sickness could cause problems for you and your baby.
