Linyilee, Neil, Smid,
Sorry for the confusion here, my fault for jumping from one way flight to return in the same posting, also other workings I take into account that I did not mention earlier make the S more rewarding in my opinion
Linyilee was quoting one way, as 25,000 miles is one way upgrade M to G? --- therefore a couple of hundred pounds one way.
Return flights
M to G is 50,000 miles, S to G is 25,000 miles, S returns 17,158 miles [M = 11,430]+ silver/gold bonus miles, make payment by VS black card and the flight has not cost me any miles at all in fact I am several thousand miles better off, add the extra 2 TPs and I feel I am getting great value, as I am also in Flying Co I get more miles from the S fare
All very subjective I know but for my circumstances I would choose an S over an M [albeit at an additional cost of £400] any day
Dream as if you'll live forever --- live as if you'll die today
