When I wrote an updated IHG Rewards Club status match piece two weeks ago (you can access it here), I noted that status matches done on or after October 1st would be valid until the end of 2014 instead of only until the end of current year.
And I now have a screenshot of an email received from IHG Rewards Club customer service to confirm it.
If you do status match now, it will be valid until December 31, 2014. To qualify for the 2015 membership year, you need to fulfill the Gold or Platinum membership requirements in 2014.
IHG Rewards Club has tried to spice up the benefits that come with both Gold and Platinum status to include an amenity (read more here) first in Europe and it should roll out in the United States next year.
