Price protection offered through Ride Pass is different than price protection offered through Uber Rewards.
Ride Pass is a monthly subscription that provides price protection on all eligible routes for an upfront price. A Ride Pass purchase provides peace of mind keeping prices consistently lower across UberX and Pool.
Uber Rewards is a loyalty program that is free to join. Benefits for Platinum and Diamond level members include price protection on one route rather than all routes. Members in these levels need to configure their route to experience the benefit.
If you are both a Ride Pass holder and a Platinum or Diamond tier member you will always see the Ride Pass pricing. Both programs work with promotions if available.
