Hello ladies,
I travelled Paris - HK on Air France at 32 weeks and no one asked me for my doctors's certificate...
Althrought I had some medical advice of my obstetrician before the flight:
1/ Don't move too much except for the yoga
2/ Don't stress at all
3/ I was carrying a suppository that I should have taken if the delivery had started. It didn't need it but in case, ask you OB to give you something to slow the delivery
4/ Show them you doctor certificate saying how long pregnant you are but don't sign any indemnity or discharge of responsability form. The pilote of the plane is fully responsible of each soul on board so advice them that you are pregnant when you purchase your ticket and it's there responsability to make sure everything's ok.
But are you sure you want to deliver overseas?
In all cases, take care,
Alexandra
