I caught a glimpse of the app when an air stewardess sat down next to me on a Delta flight. We had a nice conversation and then she looked me up by seat number and congratulated me on my Delta track record. I believe you could also save notes on each passenger. I thought that was both pretty cool and also interesting that they all had tons of data on any customer within a few clicks.
