Flying and Pregnancy: Risks and Tips

Do flying and pregnancy go well together? What's the best time to consider a flight? Here are our best tips for flying.

What are the risks for a pregnant woman?

In principle, flying has no negative effects on the health of the foetus and doesn't carry a risk of triggering premature labour.

However, if you have complications related to your pregnancy, it's best to avoid travelling at high altitude. Also bear in mind that smaller aircraft have weaker cabin pressurisation than larger ones. The body therefore has to work harder to get enough oxygen.

If you have health issues (e.g. high blood pressure, diabetes, etc.), if you have medical complications during your pregnancy, or if you have already given birth prematurely, it's advisable to ask your doctor's advice before flying.

Security gates or body scanners used in airports are not dangerous for the foetus. They don't work by emitting X-rays, but instead emit a harmless low-frequency magnetic field.

Flying and pregnancy: the best time

Pregnant women can travel without too much risk up to week 36 of their pregnancy.

• If you fly during the first trimester of pregnancy, you risk making the typical discomforts of the early months, such as nausea and fatigue, worse.
• The second trimester of pregnancy is considered the best time to fly.
• From week 28 of pregnancy onwards, certain factors (such as sitting for long periods and the effect of cabin pressure on the mother's body) can make the trip quite uncomfortable. It's therefore better to ask your doctor for written authorisation, stating that you have undergone a medical examination, the estimated date of your delivery, and a declaration that you are not at risk of giving birth during the flight.

Since the likelihood of going into labour increases beyond week 36 of pregnancy, flying is strongly discouraged from this point onwards.

A few extra tips

• Check with your airline to make sure you won't risk being denied boarding, both on the outbound and return flight. Most airlines refuse boarding from week 34, 35 or 36 onwards.
• During the flight, encourage blood circulation by walking up and down the aisle from time to time and stretching. For extra comfort, choose an aisle seat.
• Avoid staying seated for long periods, as this can cause your feet and ankles to swell. Taking off your shoes during the flight can bring relief. Be careful with closed shoes, though, as they may be harder to put back on if your feet swell. Choose lightweight shoes that adapt to your feet.
• Flying can also increase the risk of thrombosis and varicose veins. Wearing compression stockings will help protect you.
• If you're prone to nausea, pack anti-nausea medication and remedies for digestive problems in your hand luggage. Also bring a small snack.
• Before you leave (and on arrival), find out about the medical facilities available at your destination.
