most airlines have rule no after 36 weeks. before that you can't be high risk. or at least be cleared to fly by your physician. I will be flying in a few weeks.

My doctor told me only if I was in my first trimester because the motions in the air can flip baby and cause early birth CAN not DEFINATLY will but idk

ask your doctor. everyone's body is different. you're in a tight confined space, so if it's a short flight, yes, but anything over 2 hours get cleared by your doc. some airlines won't allow after a certain point without a doctors note too
