Just in answer to using a thoro fare with CX. I live in Manila but its the same for most HKG connections (TPE etc). Its cheaper in C class to book thoro with CX or BA to LHR than go with Oasis. On HKG to London Oasis are cheaper. I stopped using Oasis because their timekeeping is not the best and with limited departures and aircraft you can experience considerable delays. Everynight from LHR you have 6 HKG departures (2xCX, 3xBA, 1xVS) and others during the day. From MAN the best connection is BA to LHR and then onward. An Oasis service via Dusseldorf in C class cant compete.
