I'm in business school in new york, and we get tons of awesome speakers all of the time (CEO of Jetblue, CEO of Olgivy, etc.). Al Kelly was, however, truly great. He really ran the conversation in a fun way, as supposed to just lecturing for an hour and a half. Here's what I got out of it:

AMEX's main goal is to provide the most value it can while still making money. On average, a centurion card holder costs Amex about $2500, hence the fee. So, they are actually not covering their costs on the people who still only pay $1000.

Those are facts, and the rest of the time he asked us what we would do. So in the end, no true news. i just thought it was a really cool time.
