Chase Sapphire Preferred Credit Card
Cardholders may redeem their points at 1 cent each for gift cards or cash.
You can increase the value per point by redeeming via the Chase Ultimate Reward(r) portal. The 60,000-point bonus will be worth $750 if you choose this redemption option.
Transferring your points to Chase's airline and hotel partners is the most valuable option. Transferring points to Chase's partners can yield a higher value than transferring them to yourself, especially if your goal is to use the points for luxury travel.
Chase's 14 partners for transfer include:
IHG One Reward
World of Hyatt
