If you're carrying more than one baby, chances are good you'll deliver early. Twins are usually born around 36 weeks -- four weeks early. Triplets arrive at about 33 weeks, and quads often make their debut at 31 weeks.
Some do not restrict travel at all, no matter what stage of pregnancy a women is in, and others start to restrict at 7 months, although the majority restrict around 36 weeks. In the case of twins, some airlines will restrict travel for pregnant women at the 7th or 8th month rather than the 9th because of early labor.
