We converted points to Singapore in 2019 in anticipation of a trip to India. COVID nixed that. Now we're sitting on 222,000 Singapore miles. We also have 160,000 Chase points. We want to travel to London in Business class in May 2023 and aren't sure about the best way to book it. We live in Southern Oregon, so United is probably best, connecting through SFO. We're happy to connect anywhere though. We'll convert Chase points to KrisFlyer points. Any tips to help a rookie through the convoluted process of finding and procuring flights would be greatly appreciated!
