Flew at 32 weeks with my first; delivered at 36.5 weeks. With my second I flew in the summer at about 14 weeks. No way I was flying to my parents’ for Christmas (35-36 weeks) and chose not to for Tgiving either. It was actually nice to stay at home. Then I fell and was on crutches at Christmas so was super glad I wasn’t flying!! (She was born 39.5 weeks)
