Here's an Idea for Dealing with a Hypothetical Ban on Kids in Business/First
Obvs, the slummy way to do this is just book the kiddos into coach and fly business/first and let the FAs deal with it. But how about this: if the kids are old enough to qualify for Unaccompanied Minor status, book them in coach as UMs, fly Business/First yourself and you've basically _created_ airline supplied child care for yourself. Best of all, you don't need to worry about the airline losing your kid or something at the aiport (http://boingboing.net/2012/08/14/united-airlines-loses-a-10-yea.html) because you can check on them at will.
Why didn't I think of this sooner?
ETA: I ran this idea past my husband and he asserts -- vigorously -- that it would not go well. He is probably right, but I am really tempted.
