The article does give the stats, United does fly a significantly higher number of pets than the airline they used for comparison.
That's what I get for flying by the seat of my pants :-) thanks, in that case it wouldn't be United's fault per se; it would be like complaining that an urban interstate has more accidents than a rural two-lane. Though given the present state of higher education, one might expect that of Tulane.
(Selfie alert: I took my son to Nawlins when he graduated high school, and was thinking of where to go to college. We stopped in front of Tulane U., and I told him he couldn't go there, the school was so bad they didn't even know how many lanes there were in front of the main gate. Having lived with his father's impish puns for 18 years, he just sighed "Oh, Dad..." and went on to graduate from Rose Hulman four years later.)
