Experts usually recommend the second trimester as the best time to schedule air travel. By the fourth to sixth month, most women are accustomed to the changes of pregnancy, but aren't too large to be uncomfortable or too close to their due dates. Often, obstetricians or midwives recommend no air transportation by the seventh month. Airlines usually allow women to fly up until the last month of pregnancy, but this is not advised for women who have a history or risk of pre-term labor. Women who plan to fly close to their due dates should check the airline regulations and bring copies of their prenatal care records, including their due date, just in case.
Infants can do very well on plane trips.
Unlike adults who can chew gum, or hold their noses and blow to relieve pressure in their ears, infants usually rely on the classic technique of screaming loudly to relieve the pain. This works, but is upsetting for parents and annoying to everyone else on the flight. To avoid becoming the most unpopular passenger on the plane, parents can nurse or bottle-feed infants during take off and landing. Swallowing will help relieve the pressure in the baby's ears and keep everyone happy. It's also a good idea for parents to plan on bringing extra diapers, wipes, and changes of clothes for the baby in a carry-on bag.
