I am going to take SQ 17 next month. The spacebeds are there. Hope SQ experts will answer these questions. Which seat is the most preferable? Is there a wall in front of the first row? How about the menu? Should I do BTC? Am I correct by assuming that Wisemen will be available? Should I take SQ15 from ICN-SIN which departs 45 minutes later, therefore I can spend more time in the lounge, and earn more sectors toward PPS? Thanks!
