Planning a holiday or need to travel during pregnancy? Here's what you need to know about flying while pregnant.

The Answer: FALSE

The good news is that flying during pregnancy is generally safe and will not directly harm your unborn baby.

When is the Safest Time to Fly?

According to medical guidance, the safest time to fly is during your second trimester (weeks 14-27). This is the sweet spot because:

  • The risk of miscarriage has significantly decreased
  • You're past the most uncomfortable first-trimester symptoms
  • Early labour is not yet a concern
  • You likely still have good mobility and energy

Important Considerations

While flying itself won't cause pregnancy complications, there are practical concerns:

  • Experiencing a complication mid-flight would be problematic due to limited medical resources
  • Long flights increase the risk of blood clots (a concern for all passengers, but especially pregnant women)
  • Cabin pressure changes may cause some discomfort

When Should You Avoid Flying?

Air travel is generally not recommended after 35 weeks of pregnancy. Many airlines have their own policies and may:

  • Require a doctor's note after 28 weeks
  • Not allow travel after 36-37 weeks
  • Have different rules for international vs domestic flights

Tips for Flying During Pregnancy

  1. Stay hydrated - drink plenty of water
  2. Move regularly - walk the aisle when safe to do so
  3. Wear compression socks - to help prevent blood clots
  4. Choose an aisle seat - for easier bathroom access
  5. Keep medical records handy - especially your maternity notes
