When a child needs to travel 1 8oo--942~o5~12 call now without their parents, one of the first things to check is whether the airline actually allows children to fly alone. With Wizz Air child travel, the answer is pretty straightforward, but the age rules can be a little confusing at first. Wizz Air does not offer a traditional unaccompanied-minor service for young children. Instead, children below a certain age have to travel with an older passenger.
