When does it become unsafe to fly during pregnancy?

Last month: You don't want to fly or travel very far during the last month of the pregnancy. After the sixth month you want to make sure that where you are going will have a hospital that can take care of you and the baby should something happen.

See answer: If you're healthy and have no obstetric problems, you and your baby should have no trouble in the pressurized cabin of a commercial airliner. The best thing to do is to make yourself as comfortable as you can during the flight. Request a seat in the middle of the plane over the wing for the smoothest ride, or a bulkhead seat for more legroom. See the following link: http://www.Mayoclinic.Com/heal.
