As someone who is an SPG member and generally keeps tabs on what new promotions Starwood runs, this is anything but news. Starwood has over the past year or two, as a general strategy, struck up this kind of relationsip with a ton of companies.
- Starwood partners with Caesars Entertainment, where your SPG profile and your Total Rewards profiles can be linked. This means that loyalty shown at Caesars casinos can help you at Starwood hotels, and vice-versa
- Starwood also partners with Delta, where your SPG profile and your Skymiles profile can be linked, in a simmilar capacity - you can earn both skymiles and SPG points for Detla flights and for hotel stays.
- Now, they are doing the same with Uber... same story as above.
Obviously these companies are going to share customer data. However, if you think Starwood has the infrastructure built, capacity or talent to data mine Uber for what restaurants you go to and target hotel promotions, I think you have a bit higher expectations of them than I do. The much more immediate use of these types of partnerships is to encourage cross-brand loyalty for both companies.
