Traveling while pregnant
Any woman traveling before 36 weeks of pregnancy will be allowed to travel on a United flight without medical documentation.
A woman traveling at or after 36 weeks of pregnancy must have the original and two copies of an obstetrician’s certificate, which must be dated within three days (72 hours) prior to her flight departure. To best assure the pregnant traveler’s safety, it is preferable to have a certificate dated within one day of flight departure.
The certificate must state that the obstetrician has examined the customer and found her to be physically fit for air travel between the specified dates. The estimated birth date of the baby must be after the date of the last flight on the itinerary.
The customer should provide the original certificate to a United Representative at check-in. The remaining copies are for reference during air travel.
