Three kinds of traveller
An adult is 12 or over. A child is 2 to 11 and gets a seat. A lap infant is under 2 and travels on an adult’s lap with no seat of their own.
Which one a child counts as decides both what they pay and how many of you can travel on one booking.
What each one pays
Fares here are quoted per adult, and everyone else is a share of that:
- A child pays a reduced share of the adult fare, and the tax in full. A seat is a seat.
- A lap infant pays a smaller share again, and no tax at all.
You do not have to work the shares out. Every price you are shown already has them in it, so search for the party you are actually travelling with and the total is the total. This is why a party of four does not cost four times a party of one.
What the search will not accept
- At least one adult. Somebody has to be responsible for the booking.
- No more infants than adults. A lap needs an adult attached to it.
- A limit on seats per booking, which the passenger picker will not let you go past. Infants are not counted against it, because they are not in one.
At checkout, and on the day
Each child needs a date of birth that matches the type they were booked as. A date that disagrees is refused — see changing passenger details.
Everything about the flight itself belongs to the airline: bassinets, strollers, and whether a child may fly unaccompanied at all. Its page here has its phone number — see all airlines.
