I fly SFO-LAX RTs pretty frequently so I'm going to compare next week to yesterday - I'm hoping your stats will hold up for me as I only connect internationally a few times/year on AA but I fly them domestically a lot (to JFK and LAX so when JFK gets it, it'll be awesome).
Sadly it seems unlikely that SFO will get it, for AA anyway... But if they did it would make SFO T2 the most ruling experience of all airport terminals for me!
