my Spire runs till Dec 31, 2018. i clocked up 200K elite points over the past month, and it didn't roll over to 2019, so looks to me like they're just allowing additional two year Spire status
i'm confident they'll do it in time, otherwise they'll lose competitive advantage with all of the other programs.
makes sense for most going long to be building with a lifetime option^
i'll be eight years nxt year, when my current RA gets evaluated, if there's no news by 2019, when i have 10 yrs, i'll move over to Marriott/SPG depending on how that marriage goes, or Hilton.
