well, here's the full scenario, so that there's no confusion, both of my children have different fathers, my daughter lives with her father,and will be remaining in the USA with him, my son lives, and is moving with me, so I will be literally swapping children with fathers at the airport. My son will travel to the USA with me to go see his father, and then my daughter will return to the UK with me to visit with me. My son, I'm sure, could fly alone because he is 10, but my daughter can't, because a) she is 7, and b) her dad prohibits anyone accompanying her on her flights besides myself. All of this travel, of course, is at my expense, because of the american friend of the court system, which also is fine with me, I just want to save a penny anywhere I can during this traveling, if yanno what I mean.
