Seated Separately With a Child: Airline Duty
Seated separately child duty is a real airline obligation in the US and EU. DOT rulemaking (effective 2024) requires US carriers to seat children 13 and under with an accompanying adult at no additional fee. EU regulators press the same. Here is what to do when the seat map puts you apart.
Seated Separately Child Duty: The Law
Seated separately child duty is a 2024 DOT rulemaking obligation. Under 14 CFR 399, US airlines must seat children 13 and under with an accompanying adult, at no additional fee, to the extent adjacent seats are available at booking. The EU has issued parallel guidance; most EU carriers comply with similar practice. Despite clear rules, families still get separated at check-in when the policy fails.
The obligation is 'adjacent seats at no additional charge.' It is not 'your choice of adjacent seats.' The airline can assign any adjacent seat in your booked fare class.
What US Carriers Owe
- ›
At booking: system must attempt to assign family group adjacent seats.
- ›
If no adjacent seats in booked fare class are available: system must offer a refund of the extra-seat-assignment fee if family bought basic economy.
- ›
At check-in: if separation still exists, must proactively attempt to swap.
- ›
At the gate: must continue attempts up to boarding.
- ›
If unresolved at boarding: family can decline to travel and receive full refund.
What to Do When You Are Separated
- 1
At booking: if seats show separated, call the airline before ticketing to request adjacent.
- 2
24 hours before flight: check in, review seat map, contact airline if still separated.
- 3
At check-in counter: present the boarding passes and request fix.
- 4
At the gate: ask the agent to attempt swap with nearby passengers.
- 5
If unresolved: ask for full refund citing the DOT family-seating rule (14 CFR 399) or EU equivalent.

If the Airline Charges for Family Seating
US airlines charging a fee to keep families together with children 13 and under violates the 2024 DOT rule. File a DOT complaint immediately citing 14 CFR 399. Airlines typically refund the fee and correct the practice rapidly when named in a complaint.
