Larry's tenure was marked with a persistent disregard for elite passengers. Screwing people out of 50% EQM when they buy tickets on their corporate travel site is the best example. Continental has realized that this was just stupidity on their part and have changed this. They also implemented some pretty high fees on getting points tickets issued which really destroyed the value of their program. It's the major reason why I left.
Continental did well largely because of their fleet. I'm not sure how much Larry had to do with this.
