Traveling while pregnant
If you're pregnant and traveling before your 36th week, you can travel on a United flight without medical documentation.
If you've reached your 36th week or after, you'll need an obstetrician's certificate — the original and two copies — stating that you're fit for air travel. The certificate must be dated within three days (72 hours) of your flight departure. However, to best assure your safety, we'd prefer that your certificate is dated within one day of flight departure.
The certificate must state that the obstetrician has examined you and found you to be physically fit for air travel between the specified dates of your trip. Your baby's estimated birth date must be after the date of the last flight on the itinerary.
Please give the original certificate to one of our representatives at check-in. The remaining copies are for reference during air travel.
