I just read the page. The English could not be any clearer. If your child is over 15 then they can fly BUT, if,there is a delay, or the plane is diverted- your child is not goi g to get any treatment t beyond what an adult gets ( or doesn’t get). It is also questionable if any hotel would a.low,your child, on their own to check in! If it was my 151/2 year old,I know what I would do.
