Actually as far as the booking goes my UA MP # was in the system ok because for the flight I did from Sydney to Singapore and the Singapore to Manila sector that I flew only 3 days earlier they appeared in UA MP account almost straight away.
There obviously appears to be a "bug" in SIA's system for transferring mileage credits to partner programs and I wish I knew who to contact about it. UA say it's not their problem and are only too happy to chase down the missing mileage credits for me although they say it can take up to 3 months to come thru
