We recommend scheduling your flight around 30-32 weeks pregnant, when your belly is not too big, to ensure you are allowed on board. Please note that airlines have their own rules for flying pregnant women, but usually singleton pregnancies are allowed on board up to 36 weeks. It is also necessary to have a certificate from a gynecologist indicating the term, translated into English. Arriving in Argentina for 30-32 weeks, you will have enough time to choose a doctor and clinic for childbirth.
