Lots of airlines and hotels offer status matches. I wrote an article about status matching back in 2011 (note that some info there is defnitely outdated) when now defunct BMI gave out free Star Alliance Silver elite status.
You need to enroll by 04/18/14.
But it’s cooler than that.
-People that aren’t elite can get a 90 day challenge. Spend and fly on $1,250 worth of JetBlue flights (before tax) within 90 days of the challenge start date and you’ll have Mosaic elite status until 12/31/15.
-They will allow Southwest companion pass holders to match to Mosaic. The Southwest companion pass allows you to bring a companion on all of your flights for free and it can be earned from opening and spending on the Southwest credit card. It can even be earned by transferring Ultimate Rewards points to Hyatt and then from Hyatt to Southwest. See here for the other statuses that can be matched.
-Elites that match can also keep their status until 12/31/15 by completing the same $1,250 90 day challenge.
Mosaic gets you:
-Free flight changes and cancellations for you and everyone flying with you.
-2 free checked bags for you and everyone flying with you.
-Expedited security line access.
-Dedicated Customer Service Line
Some bloggers are saying that non-elites get Mosaic elite benefits during the 90 day challenge. It doesn’t say that anywhere and JetBlue confirmed to me via Twitter that that is incorrect.
There isn’t really a hard rule about whether programs grant benefits during a challenge period. For example United and Hyatt do while Starwood does not. Delta gives most benefits during the challenge period but does not offer lounge access during the challenge period. However most other programs only allow other elites to do a challenge or match. American is an exception in that they allow you to pay for a challenge, though they generally won’t confer benefits until you complete the flying challenge.
