Commonwealth Bank today launched a travel booking service in its banking app powered by Hopper. It's integrated to both it's whole-of-bank loyalty program, Yello, and it's credit card loyalty program, Comm Awards. CommBank Awards members can use their points to pay for travel. CommBank Yello customers receive 10% back in travel credits on hotel bookings. The travel offering includes price predictions (recommending when to book), auto price drop ($50 in travel credits if the price of the recommended booking drops), best price guarantee (credits the difference if a lower price is found), price watch (tracks flight prices) and flex it (cancel for any reason and possibly receive 80% of the cost back).
