I just received the notification this morning that my flight was changed to the SQ993 on July 24 from HKT to SIN from Silk Air. The 777-200 of this flight...how is the aircraft? I looked it up on SeatGuru, but there are 2-3 versions of the 777-200 on SQ. I'm flying in business class. I can't view the seat map on the SQ site since my changed ticket hasn't been fully processed yet.
