I have received a question about flying from Preggy – a user on Smallwalk:

Question:

I have heard you are allowed to fly till week 36-38. That is if the flying time doesn’t exceed 3-4 hours and if the pregnancy has been uncomplicated until then… Maybe we can get Smallwalk’s doctor to comment on this?

My reply:

Hi.

Mange flyselskaber accepterer ikke gravide passagerer efter 36 fulde uger, andre selskaber skal have en skriftlig lægeerklæring (< 72 timer gammel) om hidtil ukompliceret graviditet. “Retningslinier” er: 4 timer, dog i orden ved flystop hver 4.time >38 uger: ingen flyvning.

Risici, ved at flyve sent i graviditeten er for tidlig fødsel og blodpropper, specielt i benene.

Some airlines will not accept pregnant passengers after 36 full weeks other companies must have a written medical report (dated within 72 hours) for uncomplicated pregnancy. The “guidelines” are as follow:
38: weeks no flying

Risks of flying during late pregnancy are premature birth and blood clots, especially in the legs.
