Perhaps it is because Mr. & Mrs. Macska are troublemakers that US flags them...

But seriously...
my best story was I was traveling to a conference, and on my professors happened to be on the same flight. She travels a lot but is not really savvy re: upgrades and miles. So imagine her surprise when I took Row 1 on the transcon and she was back in steerage. She even brought it up the next morning at breakfast.
