For banks, their loyalty program is their app. Last month Commonwealth Bank launched travel booking and car buying in its app. The travel booking service is powered by Hopper (which delivers the same service for Uber and Capital One) and is integrated into both CBA’s whole-of-bank loyalty program, Yello, and its credit card loyalty program, CommAwards. CommBank Awards members can use their points to pay for travel. CommBank Yello customers receive 10% back in travel credits on hotel bookings.
