Seat Assignments Seat maps for most flights open 2-3 months prior to flight date. Adoptive parents rarely get even a month's notice before travel. So, if you don't like your seats or can't get advance seat assignments, arrive early, and chances are the airline will be able to help you. Bulkhead or aisle seats are usually the first choice for parents traveling with babies. The bulkhead is a row where the rows break and you have no seats immediately in front of you, allowing you more leg room and easier access in and out, and the ability to attach a bassinet.
Some airlines allow pre-assignment of the bulkhead.
Most retain those seats for airport check-in. Anytime you travel with kids, you want to keep your hands free for shuffling passports, attending to little ones, etc. A back pack rather than a diaper bag is really handy. And a baby front pack for infants is a real blessing. Carry an extra supply of diapers and formula in case you are delayed anywhere or suddenly on a 15 hour flight with a baby with diarrhea.
