Membership Benefit Year
The Elevate Status Benefit Year runs from January 1st to February 28th.
Your Benefit year runs from the time you qualify during the initial qualification year, and through to the end of the following full calendar year.
If you do not re-qualify for Elevate Status in a subsequent Membership Qualification Year, your Elevate Status Benefits will expire on February 28th after the end of the Elevate Status Benefit year.
For example, if you earn 20,000 Status Points between August 8 and December 31 2012, you will earn Elevate Silver Status for the remainder of 2012 as well as for the full 2013 Membership Benefit Year. If you do not re-qualify for the 2014 Membership Benefit Year, your Elevate Silver Status will expire on February 28. 2014.
