AA has the same type of table on their website now. They are really concerned with mileage burn. Basically, the balances at AA are getting too high and people in AAmerica get fed up when they can't get 5 tickets the Friday before Christmas to Hawaii. Strange though as CX wouldn't have a burn problem since mileage that isn't used after two years expires.

The cool thing with AA's table is that it only shows the top 20 routes in their system but lists them by day from now to January.
