Flying is generally safe during pregnancy. Airlines in the United States usually allow pregnant women to fly up
to 36 weeks of pregnancy. Late in pregnancy, you may want to limit travel–ask your doctor. Metal detectors
used for airport security checks are not harmful to the fetus. Here are some tips for a comfortable flight:

• Try to get an aisle seat so that you can walk around and get to the bathroom easily.
• The forward part of the plane usually provides a more stable ride. A seat just behind the wall dividing first class and coach, where there is extra legroom, is a good choice.
• Try to walk every 30-60 minutes up and down the aisle.
• Cabin temperature can change even on a short flight. Wear a few layers of light clothing that
  will allow you to bundle up or remove a layer or two.
• Eat lightly to avoid being airsick.
• Because the air in the cabin is dry, drink plenty of fluids. Special meals are available on some flights if you order in advance.
