You can generally fly safely until about 36 weeks of pregnancy for a single pregnancy if there are no complications, according to health experts and airline policies. After 28 weeks, many airlines require a "fit to fly" letter from your doctor confirming you are cleared to fly. For twin or multiple pregnancies, the limit is usually earlier—around 32 weeks—with similar requirements for a doctor’s note after 28 weeks. It is important to consult your healthcare provider before flying to ensure your specific pregnancy situation allows air travel and to discuss any risks or necessary precautions. Airlines may have different rules, so checking with the airline beforehand is also advised. The safest and most comfortable period to fly during pregnancy is generally the second trimester (weeks 14 to 27). Key points:
- Most can fly safely until 36 weeks for a single pregnancy.
- A doctor's note is often required after 28 weeks.
- Twin/multiple pregnancies usually have earlier limits (32 weeks).
- Consult your healthcare provider before flying.
- Airline policies vary; always confirm before booking.
- The second trimester is the recommended travel period for comfort and safety.
