At AS, we also have the ability to buy confirmed revenue tickets at 20% off for ourselves and eligible dependants. That goes for any ticket at any price as long as it is available for purchase.

There are also positive space "credits" we receive from time to time for exceeding cust.service or on time levels. Each credit can be used for one-way confirmed positive space travel booked as HK. We pay some imputed income taxes on those though, but still a great deal when you don't want to play the waiting game.
