Parents should’t have to pay a fee to sit next to their children when flying, according to the White House, which is moving to ban airlines from charging families extra to be seated together.

Under a rule proposed Thursday by the Department of Transportation, airlines would be required to seat parents and kids 13 and younger together free of charge when adjacent seating is available at booking.

The idea of seating adults with their younger children “is common sense and also seems like something that should be standard practice,” U.S. Transportation Secretary Pete Buttigieg said at a news briefing on Wednesday. “As someone who has personally experienced flying with toddlers,” Buttigieg said he knew first-hand that families traveling with little ones do not need added difficulties.

The extra cost can be the difference in whether families can afford flights for vacations or to see friends and relatives, the administration argued, noting its proposal would save a family of four up to $200 roundtrip if seat fees are $25 each.

For children too young to fasten their own seatbelts or feed themselves, being seated next to a parent is crucial, yet those that don’t want to pay more often end up pleading with other passengers to switch seats. If passengers opt not to swap seats, they may end up next to an unsupervised child, stressing out the youngster, parent, flight attendants and travelers, DOT said.

President Biden called on Congress to ban family seating and other so-called “junk” fees early last year, with Buttigieg then urging the 10 largest airlines to voluntarily ban the fees. Four complied: Alaska, American, Frontier and JetBlue. 

Congress gave the DOT explicit authority to propose its rule as part of the bipartisan FAA Reauthorization Act of 2024, the transportation secretary noted. “We are confident that we are well-founded in our authority, but it helps to get reassurances from Congress,” Buttigieg noted in answering a question about whether the proposal might be challenged in court.

In addition to banning airlines from charging fees to seat those 13 or under next to a parent or accompanying adult, the proposal would require that airlines seat parents next to their kids within 48 hours of booking when adjacent seats are available. 

If adjacent seats are not available, carriers would be required to provide passengers with full refunds or the option of waiting to see if family seating frees up. If not, airlines would have to offer the option to rebook for free or stay on the flight in nonadjacent seats.
