Because oxygen and air pressure decreases in the upper atmosphere, transportation of expectant mothers has been restricted to some extent. Expectant mothers are advised to consult their doctor before booking a journey and carry documentation listing their expected delivery date.
- 1. Expectant mothers whose pregnancy does not exceed 32 weeks can be transported as regular passengers except when they have been advised by doctors that they are not fit for air travel.
- 2. If passengers are over 32-weeks pregnant, they are generally not allowed to board a plane. In the case of special circumstances where passengers are over 32-weeks but less than 36-weeks pregnant, they have to file an application with a CSN direct sales office before booking tickets and provide diagnosis proof that contains the following information:
- - Name and age of passenger;
- - Date of pregnancy;
- - Flights and dates of travel;
- - Suitability for air travel;
- - Whether or not special on-board care is required, etc.
(The aforementioned diagnosis certificate must be issued within 72 hours prior to the flight departure, and contain the official stamp of a hospital not below the county level and signed by the doctor before validation.)
- 3. Women with singleton pregnancy for 36 weeks and more or multiple pregnancy for 32 weeks and more are not accepted for carriage.
