Can an airline sit a child away from parent UK?

Families, children and infants Young children and infants who are accompanied by adults should ideally be seated in the same seat row as the adult. Where this is not possible, children should be separated by no more than one seat row from accompanying adults.



Under UK Civil Aviation Authority (CAA) guidelines in 2026, airlines are strongly encouraged to seat children with their parents, but it is not a "guaranteed" legal right unless you pay for seat selection. The CAA states that children under 12 should be seated with at least one accompanying adult, often in the same row or an adjacent one. For toddlers and infants, airlines almost always ensure they are next to a parent for safety and supervision. However, if a flight is extremely full and a family has not pre-booked seats, they may be split across the aisle or into "back-to-front" rows. Most major UK carriers, like British Airways and Virgin Atlantic, have internal policies to keep families together, but low-cost carriers may be more rigid unless a fee is paid. It is a high-value peer tip to check in as early as the 24-hour window opens to secure the best remaining seats, or simply pay for selection during booking to avoid the stress of a "scattered" cabin.
