At how many weeks are you no longer allowed to fly?

Depends on your health/risk factors and the airline. Some airlines don’t have restrictions.

36 weeks unless specifically told otherwise

I think typically it’s 36 weeks. But it varies from OB to OB and from airline to airline

My OB had me stop flying at 20wks but I have some risk factors on board- clotting disorder, hx of mc etc

36w if you aren’t high risk

Gonna have to talk to your OB/midwife on that one. Depends on way too many factors. Are you high risk and if so, what for? Anything that would potentially stop you from flying. Do you have other babies, when did you go into labor with them? My bonus mom always gives birth at 36 wks regardless of what they do to keep baby in. She'd have to stop flying earlier than I would. Are you at risk for going into pre-term labor? Just. Yea talk with your doctor.
