When Can You Fly in Pregnancy?
Most experts agree that airplane travel is safe before 36 weeks of pregnancy. Even so, your health care provider may advise against flying in certain situations, such as if you have a high-risk pregnancy complication. Some airlines also have domestic and international flight restrictions for pregnant people, so it’s best to do your research.
Here’s what to know about flying during pregnancy, with important tips to know before booking your tickets.
Is It Safe to Fly During Pregnancy?
Flying is usually considered safe during pregnancy. “Pregnant women can observe the same basic precautions for air travel as the general public,” says Raul Artal, MD, former vice chairman of the American College of Obstetricians and Gynecologists (ACOG) Committee on Obstetric Practice.
If you’re relatively healthy, then you’re probably clear to travel until 36 weeks (though some providers prefer you stay closer to home as your due date approaches). High-risk patients may be advised not to fly after 24 weeks; in some cases, they might be encouraged not to fly at all. Flying guidance also differs for twins and multiples.
Note that some airlines restrict pregnant people from flying internationally a bit earlier (often between 28 to 35 weeks). Others might require proof of your due date. Check with your airline provider for more information.
Airport X-Rays and Radiation During Pregnancy
Airport screening equipment and metal detectors won’t harm your fetus, according to the U.S. Transportation Security Administration (TSA). And while you may have heard that radiation increases with higher altitudes, pregnant people don’t need to worry, because risks to the fetus are “negligible,” says ACOG.
Who Should Avoid Air Travel While Pregnant?
According to ACOG, travel is not recommended for pregnant people with certain “medical or obstetric conditions” like preeclampsia and premature rupture of membranes (PROM), or those who are at risk of preterm labor.
Essentially, if you have a condition that could be made worse by flying—or that might require emergency care—you should think twice before hopping on a plane. Most pregnancy emergencies happen in the first and third trimesters, according to ACOG.
In some cases, people with pregnancy complications can travel but must stop earlier than 36 weeks. Talk to your health care provider for their recommendations.
There’s one extra thing you should consider doing before booking a flight during pregnancy: Opt for travel insurance. If your health care provider recommends you stay home—or if you experience any concerning symptoms like bleeding, abdominal pain, swelling, headaches, vision changes, or decreased fetal movement—you’ll want to postpone or cancel your plans and see your doctor as soon as possible.
Preventing Blood Clots During Flights
One thing pregnant air travelers should take extra precautions to avoid during all trimesters? Blood clots, which pregnant people are five times more likely to develop—especially during long periods of travel like airplane flights.
Signs of a blood clot in the legs include swelling, pain or tenderness, and warmth or redness on the skin. If the blood clot breaks off and travels to the lungs (called a pulmonary embolism, which is life-threatening), you might experience chest pain, a cough that might contain blood, and breathing difficulties.
To help minimize your risk of blood clots, you can:
- Book an aisle seat, and make sure to walk around every so often
- Wiggle your legs and toes while seated
- Stay hydrated and avoid caffeine
- Wear loose clothing
- Consider wearing compression socks (after getting approval from a health care provider)
Tips for Traveling While Pregnant
Follow these tips to stay safe and comfortable during plane rides while pregnant.
- Before embarking on your journey, research hospitals located near your destination should an emergency arise. ACOG also recommends a prenatal check-up to confirm your due date, discuss any symptoms, and see whether you need vaccinations.
- Choose clothing that’s loose and breathable, and opt for layers that can be added or removed.
- Wear your seat during the entire flight to protect against unexpected turbulence. Place the seat belt low on your hips, below your belly.
- Limits gas-producing items before flights to ease potential discomfort.
- If you’re suffering from morning sickness, you may want to check with your health care provider about bringing anti-nausea medicine with you.
