On most major airlines in 2026, families with young children do not board "first" (meaning before everyone else), but they are given a dedicated "Family Boarding" window that usually occurs after the premium and elite groups. On Southwest Airlines, family boarding (for those with children age 6 or younger) occurs between Group A and Group B, ensuring families can find seats together before the plane fills up. On legacy carriers like Delta, United, and American, "Pre-boarding" is usually reserved for those with disabilities or active military, with families of children under 2 following immediately after. In 2026, many airlines have refined these rules to speed up the process; for example, if you have already paid for "assigned seating" with your children, the airline may encourage you to board with your regular group to reduce congestion. It is essential to listen to the gate agent's specific announcements, as "family boarding" is a courtesy rather than a guaranteed right, and the age cutoff for "young children" can vary from 2 to 7 years old depending on the airline's specific policy.
