Didn't see a post here about it. There is a similar post in the Hilton forum, but figured this could stand on its own here.

I've already been earning DL miles on my Lyft rides and just received an email earlier this week that there is a Hilton partnership, also. As my secondary program, it's good to keep my Hilton account active and the incremental points wouldn't hurt. I registered on Tuesday, connected my accounts, and literally 2 minutes later ordered a Lyft. I checked my account today and points have already posted. It earns 2-3 points per dollar (excluding tax, tolls, tips, fees). Confirmed that it's stackable with the DL and B6 partnerships, also. I just confirmed DL miles for the same ride.
