Generally, women are not allowed to travel by air after 36 weeks for domestic travel, and after 28 to 35 weeks for international travel. The decision on whether to travel and how far to travel at any time during pregnancy should be a joint decision between you and your healthcare provider or midwife.
However, many obstetricians advise against non-essential long-distance travel with your baby until they are at least 3 months old. Consider using an air ambulance to avoid health complications for both you and your little bundle of joy.
