With the rise of basic economy and budget airline models that charge extra for seat selection, it’s become a lot harder for groups, but especially families with kids, to secure seats next to each other. And that’s a sore spot for many parents who travel: Once a child is above two years old, they’re typically no longer considered a lap-seat infant. And of course, small children want to be with their parents—so should you have to pay more just because you’re a family if not enough free, consecutive seats are left? Airline family seating policies vary by airline, but the problem has apparently become so widespread that the Department of Transportation (DOT) is addressing it, though not guaranteeing you won’t have to pay for it.
