Best strategy for reward tix DTW-LHR with 4 SWU's
I am a first time recipient of 4 SWU's via my platinum status granted through Amex Centurion. I'd like to try to use these in the Fall (Sept/Oct) to go DTW-LHR on a Wed-Sun trip. Ideally would like to find the best combination of approximately 200,000 banked miles/SWUs/$ to get there. 2 travelers. I've read the sticky thread on low tier business awards, but still searching for best strategy. Any help greatly appreciated. Thank you
