Can You Fly When Pregnant? Is it safe?

When pregnant, many changes occur in the body, from physical appearance and dietary habits to exercise routines, and even sleeping positions that used to be comfortable might not be so anymore. Traveling is no exception. Pregnant women may wonder if air travel is safe for the baby. Therefore, we have gathered recommendations to ensure that air travel during pregnancy is as safe and comfortable as possible.

You should avoid international travel if:

You are pregnant with uncontrolled health conditions such as severe anemia or heart disease.
You have multiple pregnancy or fetal growth restrictions.
You have a current or history of placental abnormalities such as placenta previa.
You have vaginal bleeding or a risk of miscarriage.
You have a history of miscarriage, ectopic pregnancy, premature labor, or premature rupture of the amniotic membrane.
You have a history of hypertension , preeclampsia, and blood clots.
You have cervical instability or frequent contractions requiring uterine muscle tocolytics.

Your doctor may also advise against travel to high-altitude locales (above 12,000 feet), regions with disease outbreaks, or where live-virus vaccines are prerequisites for travel to the areas.

While on the plane, you may experience a slight increase in blood pressure and heart rate, which are generally not harmful. Upon arrival at the destination airport, security procedures may involve a body scan, which is safe for pregnant women. However, if you are concerned, you can request a standard pat-down or metal detector scan instead.

Occasional travelers need not worry about radiation exposure, but frequent flyers, such as business travelers, pilots, and flight attendants, might exceed safe radiation levels. Pregnant women who are frequent flyers should seek medical advice.

Travel Recommendations for Each Trimester of Pregnancy

Pregnant women should have a health and pregnancy assessment to ensure they are fit for travel.

First Trimester

During the first trimester, air travel is possible. Passing through metal detectors poses no harm to the fetus. Postpone the trip if there is a risk of threatened miscarriage.

Morning sickness commonly occurs during this trimester, so pregnant women should consult their doctor before embarking on their travels. Doctors may prescribe medications for nausea and headache.

Second Trimester

The second trimester, between 14-28 weeks of pregnancy, is the best time for travel. Morning sickness usually subsides, and pregnancy is not too far advanced, making it easier to move around. When flying during this period, staying hydrated is crucial. Discuss with the doctor whether compression stockings are necessary. Additionally, search for and keep contact information of hospitals at the destination in case of emergencies.

However, women carrying multiple pregnancies should avoid travel during the second trimester due to the higher risk of complications.

Third Trimester or Last Trimester

During the third trimester, women who are healthy and at low risk for preterm labor, preeclampsia, or placenta previa can still travel by air until 36 weeks of pregnancy. Choosing a destination within a manageable distance can lead to a more enjoyable journey. Always consult a doctor to obtain a medical certificate before traveling. It is crucial to be mindful of deep vein thrombosis (DVT). Wearing compression stockings, moving the legs and ankles regularly while seated, and taking frequent walks is recommended. Avoid holding in urine, as urinary tract infections can lead to preterm labor.

Planning the trips for traveling while pregnant

When planning to travel by plane, pregnant women should consult with their obstetrician, especially if they are at high risk of pregnancy complications. Air travel is generally not permitted for women who have reached 36 weeks of pregnancy. Securing comprehensive travel insurance is also essential, ensuring that it covers emergency changes to travel plans due to potential obstetric emergencies such as vaginal bleeding, abdominal pain, or decreased fetal movement. Women diagnosed with preeclampsia, experiencing premature rupture of membranes, or at risk of preterm labor should refrain from traveling.

Preparing for the Journey

Visit the doctor to obtain medical clearance. During this consultation, discuss the following points with your healthcare provider:

Get vaccinated before the journey, such as influenza or COVID-19 vaccinations.
Compression stockings for augmenting blood circulation during the flight.
Anti-nausea medication
Gas and diarrhea prevention. The change in altitude during flights can cause intestinal gas expansion and abdominal discomfort. Avoid consuming gassy foods before flying. Visiting another country may expose you to bacteria that cause traveler's diarrhea. You should bring along diarrheal remedies.
Request recommendations for doctors and hospitals in your destination city or country; your doctor may have connections or access to a medical network abroad.

Inform the airline about your pregnancy. They may be able to provide additional assistance to make your flight more comfortable.

While Onboard

Refrain from eating beans, cabbage, broccoli, and carbonated beverages, which can cause bloating and gas forming.
Wear comfortable clothes and compression stockings.
Buckle your seatbelt under your belly and keep it fastened at all times; turbulence can occur unexpectedly.
Drink plenty of fluids. There is low humidity in the cabin air; therefore, you can readily become dehydrated. Dehydration can thicken blood, reducing blood flow to the uterus and increasing the risk of blood clots. It is best to drink water to stay hydrated.
Get up and walk every 30-45 minutes during a smooth flight to improve blood circulation. Flex and extend your ankles and elevate your legs to improve blood flow and reduce the risk of swelling and deep vein thrombosis.
Choose an aisle seat for easy bathroom trips, a bulkhead seat with spacious legroom, or a seat over the wing that provides the smoothest ride.
Pack healthy snacks such as trail mix, nuts, whole grain crackers, fruits, or peanut butter in your carry-on.
Bring hand sanitizer, alcohol spray, and antibacterial wipes to sanitize your tray table, TV remote, and armrests. Wash your hands with soap as frequently as possible. Avoid touching your face, and wear a face mask.
