Second, my flight from FRA to SIN is SQ325 which I belive is one of the new 777-300ERs with the new interior. Has the reconfiguration had any impact on the the booking classes SQ is using? Can old A-class become their new business-class code? I need to manage my expectations a little bit here, before investing in some smart carry-on luggage to match the first-class experience of SQ

For business class, SQ is now using booking class Z above full fare class C for selling the new seats at a incredible high fare, but nothing has changed at for first class. For RTWs, SQ uses A regardless of old or new seats, and SQ 325 defintely has the new seats - enjoy!
Now if you are booked in First on SQ, you want to make sure you are booked in First on all other segments as well (where offered), right?
