The safest time to fly during pregnancy is before 37 weeks, or before 32 if carrying twins.
That’s according to new advice from The Royal College of Obstetricians and Gynecologists.
The college says flying is not harmful to pregnant women and babies during a low-risk pregnancy, but there may be side effects.
Everyone who flies is exposed to a slight increase in radiation, but there is no evidence that flying causes miscarriage or early labor.
