Two suggestions for AC marketing:

- show the number of each gift remaining at each level, and also show how close the next X altitude members are. Get some competition going among your best customers!

- better yet, don't just hand out the gifts willy-nilly. Wait until the end of the year. Those who qualified for gifts can then compete for them on live television, with the higher miles earners getting a head start or something. There will still be one more Hunger Games movie coming out, so you could even synergize with the movie studio on a joint marketing effort.
