When traveling on an airplane many parents find that bulkhead seating at the front of each section provides more comfort while traveling with a toddler. These seats have no seating in front of them and allow for more leg room, ability to change the baby, and room to stand or play for the toddler.
Passengers may request a bassinet for their child which is attached to the wall while in-flight. Bulkhead seating and bassinets must be requested ahead of time.
