T-330 means 330 days prior to departure — when the schedule opens. In years past, UA would habitually open some number of upgrade seats when the flight first came onto the schedule. I haven’t noticed that recently, but if cfischer says he has, I believe him. . It’s rare that this would do me much good personally, becuase I’m normally requalifying late in the year, so there’s very little time when I have PlusPoints that are good for 330 days anyway. Buf if you requalify in, say, April, you’d have almost a whole year to use PlusPoints 330 days prior to departure.
