Generally, if you’re pregnant and not experiencing any complications, air travel is considered safe up to 36 weeks of gestation. However, it’s always recommended to consult with your healthcare provider before you plan to fly.
Your healthcare provider might advise against air travel if you have certain pregnancy-related conditions that could be exacerbated by flying or require urgent medical attention. These conditions may include a history of miscarriage or unexplained vaginal bleeding, severe anemia, or poorly managed high blood pressure or diabetes. If you experienced preeclampsia in a previous pregnancy, a condition characterized by high blood pressure and protein in the urine, flying might not be recommended. Similarly, if you are expecting twins or multiples, air travel might be discouraged.
It’s important to inform your healthcare provider about the duration of your flight, as longer flights can pose different considerations. Furthermore, be aware that some airlines have specific policies regarding pregnant passengers, especially on international routes. Always confirm with your airline about their regulations before making travel arrangements.
After the 36th week of pregnancy, many healthcare providers will advise against flying. Additionally, numerous airlines restrict air travel for pregnant individuals beyond 36 weeks. Airlines may also require a letter from your healthcare provider confirming your gestational age and stating that air travel is safe for you.
If your healthcare provider approves air travel and your schedule is flexible, the second trimester is often considered the most favorable time to fly. During this period, the risks of common pregnancy emergencies are typically at their lowest.
When you do fly while pregnant, consider these safety tips:
- Buckle Your Seatbelt Securely: Always keep your seatbelt fastened while seated, positioning it comfortably below your belly.
- Stay Hydrated: The low humidity environment in airplanes can lead to dehydration, so drink plenty of fluids throughout your flight.
- Be Mindful of Gas-Producing Foods: Avoid consuming gassy foods and drinks before flying, as gas expansion at higher altitudes can cause discomfort. Examples include broccoli and carbonated beverages.
- Plan for Medical Needs: Familiarize yourself with how to access obstetric care at your destination if needed. Carry copies of your medical records in case you require medical attention while traveling.
Understanding the Risk of Blood Clots
Air travel can slightly increase the risk of developing blood clots in the legs, known as venous thrombosis. This risk is further elevated during pregnancy. To mitigate this risk, movement is key. Make an effort to walk in the aisle every hour during your flight. If you are unable to leave your seat, regularly flex and extend your ankles. It’s generally advisable to avoid wearing tight clothing, as it can impede blood circulation. Consider wearing compression stockings to aid blood flow, especially on longer flights.
Radiation Exposure During Air Travel
Exposure to radiation during air travel at high altitudes is generally not considered a significant concern for occasional flyers during pregnancy. However, individuals who fly frequently, such as pilots and flight attendants, may be exposed to higher levels of radiation that could be a concern during pregnancy. If your job requires frequent flying during pregnancy, discuss this with your healthcare provider.
