boy, my habit of flying AA burned me on this trip. I used to pack 3 batteries for travel, but once i became an aa loyalist, just brought my igo juice.
But b/c AA was late, I was rebooked on UA from BOS>LAX (5 hours work lost); and surprisingly the Cathay (dragonair) flight in business class from HKG>DLC didn't have power either.

on this dimension, i really think aa is the best...
