Air travel during pregnancy is generally considered safe for women who have healthy pregnancies, but it’s important to check if your medical scheme or health care provider approves air travel.
The best time to fly may be in the middle of your pregnancy, at about weeks 14 to 28. This time is when you are likely to feel your best, and the risks for premature labour or miscarriage are the lowest.
The chances of going into labour are higher after 37 weeks, and some airlines will not let you fly towards the end of your pregnancy. Do some research on the particular airline’s policy about air travel during pregnancy as it varies for different carriers.
Tips for when you fly
- Pre-select your seat – an aisle seat will give you the most space and comfort.
- During the trip, fasten the seat-belt under your abdomen and across the tops of your thighs.
- Low cabin humidity can lead to dehydration, so drink plenty of juice and water.
- If possible, take occasional walks up and down the aisle to promote circulation. If you have to remain seated, extend and flex your ankles often.
Risks – take note
Long-distance travel (longer than five hours) carries a small risk of blood clots (deep vein thrombosis). Drink plenty of water and move about regularly – every 30 minutes or so. You can buy a pair of support stockings or knee-high socks specially designed for flying at the pharmacy, which will reduce leg swelling. For the best protection, put the socks or stockings on before you get out of bed in the morning and keep them on the whole day.
Speak to your doctor about flying if you’ve had medical problems during your pregnancy, such as:
- spotting
- diabetes
- high blood pressure
- a previous early birth
- a clotting disorder
- sickle cell disease
- placental insufficiency
Your doctor may restrict travel of any type after 36 weeks of pregnancy or if you’re at risk of preterm delivery.
Radiation exposure associated with air travel at high altitudes isn’t considered a problem for most travellers, but it may be different for frequent fliers. Pilots, cabin crew and others who fly often might be exposed to more radiation than is considered safe during pregnancy. If you have to fly frequently during your pregnancy, it is important to discuss it with your doctor.
