Committee opinion: number 264, December 2001. Air travel during pregnancy.
In the absence of obstetric or medical complications, pregnant women can observe the same general precautions for air travel as the general population and can fly safely up to 36 weeks of gestation. In-craft environmental conditions, such as low cabin humidity and changes in cabin pressure, coupled with the physiologic changes of pregnancy, do result in maternal adaptations, which could have transient effects on the fetus. Pregnant air travelers with medical problems that may be exacerbated by a hypoxic environment, but who must travel by air, should be prescribed supplemental oxygen during air travel. Pregnant women at significant risk for preterm labor or with placental abnormalities should avoid air travel. Because air turbulence cannot be predicted and the risk for trauma is significant, pregnant women should be instructed to continuously use their seat belts while seated, as should all air travelers. Pregnant air travelers may take precautions to ease in-flight discomfort, and although no hard evidence exists, preventive measures can be employed to minimize risks.
