In past years, CO provided Elites with complimentary Gold HHonors status with Hilton (after 4 stays), free Emerald Club and Avis Preferred car rental "elite" programs, and Gold status with Starwood hotels.

Does CO or their marketing providers still provide any elite access or fast-track-to-elite status in any other program?

I think they sent me a mailing with complimentary Gold-level status in a Latin American hotel chain a few weeks ago, but I don't do much in the way of travel there.
