What happens if my child turns 2 during a trip?

Additional infants under 2 years old must be ticketed and occupy an infant safety seat or in a separate aircraft seat. The infant must be under 2 years of age for the duration of the trip. If they turn 2 during a trip, they will need their own seat for the remainder of the trip.
