Hi folks. Please can you help me decide what to do and when re my Star Alliance memberships? I've got LH, no status, but a few hundred k miles left. I've got Singapore, Silver, based on one first class LHR-SIN in January, and one EDI-SFO business return on United. In my new job it looks like I will be doing United EDI-SFO and EDI-EWR returns quite frequently (6-8 times per year at a guess) - because United is the only direct flight to EWR, and the EWR connection to SFO works quite well. So the questions I have are (1) whether it is worth consolidating my Star Alliance memberships into one, and if so to whom, when (e.g. when I hit gold on Singapore), and how? And (2) if consolidation is not an option, isothere any merit in me abandoning current memberships and joining United?

thanks
