There are no uniform rules and generally binding regulations regarding the air carriage of pregnant women.
Individual airlines set their own rules with regard to the transport of pregnant women in the Conditions of Carriage and due to this reason, expectant mothers are advised to acquaint themselves with these rules before their flight. The general rule is that a pregnancy that is without complications until the end of the 28th week (in some cases the 26th week), there are no limitations imposed on the travel of pregnant women. Between the 28th and the 36th week, a pregnant woman can only travel with a valid confirmation from her doctor (not older than dated 7 days before the departure).
Some airlines go as far as to set out rules for individual stages of the pregnancy in their Conditions of Carriage, after the end of which the expectant woman is not allowed to take the flight due to the risks associated with it.
In order to let pregnant women avoid potential misunderstanding in the course of the checking in process, they are advised to always travel with their pregnancy book and a ‘fit to fly’ certificate.
Airlines do not offer suggestions and warnings to pregnant women within their Conditions of Carriage, as these are very individual and subject to the individual woman’s health condition. Pregnant women should always consult their doctor before purchasing an air ticket.
As regards flight itself, pregnant women are never allowed to sit by the emergency exits; otherwise, same rules apply as in the case of other passengers (including the obligation to fasten the safety belt during the flight).
When passing through security control, pregnant passengers can ask for a manual security check if in any doubts. However, the metal detector frame does not have any side effects on the health of the passenger or her baby.
