Will airlines separate me from my child if I don't pay?

Most airlines have policies to seat children under 12 with at least one accompanying adult, but it is not a legal guarantee. Always pay for seats if you want peace of mind.

Can I switch seats at the gate?

You can ask, but gate agents are often busy. If you didn't select seats in advance, you are likely stuck with whatever is left, which is usually middle seats in different rows.

How to Book Airline Seats for Families

Select seats at the moment of booking to ensure you are seated together, rather than waiting for check-in. If the airline charges for seat selection, pay the fee; it is cheaper than the cost of a missed connection or a split family on the day of travel.

Check the seat map before buying. Do not pay for the ticket until you view the seat map. Go to the airline’s website, initiate a dummy booking, and look for a 'Seat Selection' preview to ensure there are still blocks of seats available together.
Prioritize rows with bulkheads or lavatory access. If traveling with an infant, bulkhead rows provide extra floor space for a bassinet. If traveling with toddlers, look for seats near the rear lavatories to minimize the distance you have to walk during frequent bathroom trips.
Use third-party seat trackers. If the only available seats are separated, use tools like SeatSpy or ExpertFlyer to set an alert for when better seats open up. Airlines often release blocked 'preferred' seats 24–48 hours before departure.
Call the airline to link PNRs. If you booked tickets separately or across different platforms, call the airline's customer service desk to link your Confirmation Numbers (PNRs). This prevents the system from automatically separating family members during seat assignments.
