All you need to know is that you didn't get upgraded.

Or maybe you have a philosophical problem with kids in F. If that's the case, then (as someone already pointed out) US disagrees with you and your opinion isn't particularly relevant.

A few months ago my family and I flew in F on a DCA-PHX-SNA-PHX-DCA vacation. The dirty looks that my 2 kids got made me smile at these peoples' self-induced misery. If you want to resent what other people do with their money or miles, go for it. But I can assure you we had a great time up in F (and were treated very well by all of the FAs) and we'll continue to travel that way as money and miles permit -- your indignation notwithstanding.
