Ultimate Rewards Travel Redemptions — Book travel through the Ultimate Rewards travel center and redeem points to pay for your plane tickets, hotel stays, rental cars or experiences. As a holder of the Chase Sapphire Preferred or the Ink Business Preferred, you’ll get a 20% discount when paying with points, so each point is worth 1.25 cents (e.g., a $100 hotel room would only cost 8,000 points). And if you have the Chase Sapphire Reserve, your points are worth 1.5 cents apiece toward redemptions through the portal. 3. Transfer to Travel Partners — You can transfer Ultimate Rewards points to 9 airline programs (British Airways, Flying Blue, Korean Air, Singapore Airlines, Southwest, United, Virgin Atlantic and the more recent additions of Aer Lingus and Iberia) and four hotel programs (Hyatt, IHG, Marriott and Ritz-Carlton). All transfer ratios are 1:1, and you must transfer in 1,000- point increments. https://thepointsguy.com/guide/redeeming-chase-ultimate-rewards-maximum- value/
