Marriott’s acquisition of Starwood closed in September and they immediately made it possible to match status across the programs, and to move points back and forth at a ratio of 3 Marriott points to 1 Starpoint.
They’ve begun to align their programs in some subtle ways. One of the first things, even before the merger, was Marriott offering 4pm late checkout to Gold and Platinum elites, introducing experiential redemptions in the vein of SPG Moments and testing a concierge program for top elites similar to Starwood Ambassador.
