Over at RAH we see the fuel programs from all three legacies. AA is by far the most stringent and sometimes downright sketchy when it comes to fuel.

Last year I was in recurrent training with the former E-170 Program Manager. Fuel came up in conversation and he told the story of how AA came to us around a decade ago and said "You guys are carrying too much gas." "How do you know that?" we said. Their reply: "Our bean counters have looked at your diversion numbers vs. everyone else's and you are diverting less than any other carrier in our system. That must mean you are carrying way too much fuel."
