Holiday to Japan.

hihi! are you carrying one only? my obgyn says in general they recommend for singleton regular pregnancies, that flying up to 32-34 weeks is fine :) twins, 28 weeks. take note budget airlines stop accepting pregnancies earlier..while some airlines allow up to 34-36 weeks. final thing is travel insurance in general also covers up to 28 weeks only, I think beyond that they may not cover or they'll have exclusions

For travelling wise on long haul flight or about minimally 8 hrs, you still need clearance from your doctor/gynae to ensure you are fit and healthy to fly.

Check the airline whether u need a clearance from gynae. SIA is 28 weeks if I m not wrong.
