Please can someone advise me on an in-expensive way to go from SIN to PEK without going all the way around from SIN-NRT-PEK? I'm going to SIN on NW(MSP-NRT-SIN), however, I want to visit PEK for a couple of days and return to SIN for my flight back to the US. So far the flights I've found go from SIN-NRT-PEK and are quite expensive. What are my options? Thanks.
