Also have five customer service "Systemwide Upgrades" that are expiring next Nov/Dec/Jan. Pretty much same deal as 1K but you can use these on single flight number use, whether east coast USA to Asia/Pacific or LAX or SFO to Europe etc, etc. Good on any published fare, also fully transferrable, upgrade confirmable a year in advance etc, regardless of MP status etc. Would also do a trade, some or all, for similar dated 1K SWU - slanted in your favour.
I've had several agents tell me that these are sales upgrades. Some of the cheaper international fares (US-Europe) prohibit the use of these.
