US Airways Dividend Miles (Pre-FlightFund Merger) - DM Award on SQ - Will they downgrade me?

I am on a 90K Asia C class award in November. We are going over on UA and back on SQ. It is booked in "I" class for business class. We have business class seat assignments on the new SQ SIN - EWR nonstop. I have heard that they have been putting "I" class in Executive Economy on that flight.

Any truth or am I just scared for no reason?

Someone has told me their is an upcharge of miles for the new A345 on that super long haul?

Argh! Please help assure me that I can rest comfortably in C class!

SQ has a new policy about intra-Asia Star awards that book in Economy Class when Business Class miles are deducted, or something like that, but the problem has distinctly been said not to apply to the EWR-SIN and LAX-SIN A345 non-stops. If you book a Business Class award, you're in Raffles (Business Class).

Big thread about it in the UA forum, but since I don't fly SQ, I only paid it glancing attention, so...

Appreciate the help!
