Congratulations for grabbing the F award. I know many flyers had taken there chances for many routes on SQ in anticipation for a change in equipment such as into A380 or 77W.
What I heard it is possible that SQ11/12 might be swapped to 77W, and SQ1/2 might go back to 744. In any case, F is still F. And yes, I like the service on SQ11/12.
