Sorry, that was from many years ago back when Centurion first started. I did find a letter from 2004 that lists the benefits, but the Triple upgrade was gone by then. This letter just says complimentary upgrades when you reserve a mid-size or larger. It also has the courtesy pickup and dropoff for private planes, complimentary child seats and ski racks, 4-hour grace period, extended weekend rates beginning at 7am on Thursday, etc.
