SFO deal radar June 10 — CSP Hyatt 4:3 breaks today; three fresh domestic fares

The June 10 issue leads with breaking news — Chase announced today that the Sapphire Preferred's World of Hyatt transfer ratio drops to 4:3 (first non-1:1 in UR history), with the Sapphire Reserve exempt at 1:1. That change, combined with the CSR's best-ever 150K bonus expiring in 5 days (June 15 at 9 AM EDT), makes the two decisions tightly interconnected. On fares, three D1 domestic deals are fresh: United SFO↔Nashville at $155 BE, American SFO↔Chicago at $213 BE, and United BWI↔SFO at $217 BE. United SFO↔Singapore nonstop at $696 BE is D2 and worth booking today. Yesterday's Seoul and Hanoi leads are D4 and treated as expired. Points deadlines covered: Alaska Saver earning ends today (last day), Citi TYP → Preferred Hotels/Wyndham expire June 13 (3 days), and Chase UR → Virgin Atlantic 30% is new through July 14.
