We're in a bit of a bind as we're mvoing to NYC and I need to go before the family, dh needs to stay a bit longer to finish up the house. We're thinking of using the BA skyflyer service. Children will be 5.5 and 8.5. I'm thinking they are a bit too young, at least the little one, but spoke to someone from BA who told em that it's very safe and that the kids are supervised all the time. So now I'm a bit torn. Any thoughts?
