Clean one-stop option via Hong Kong. Both legs avoid advisory zones. Strong choice if direct flights are sold out or if Cathay Pacific connectivity is preferred.
Worth knowing
Hong Kong is a consistently high-performing hub. The added connection time (approximately 1 hour) means slight exposure to missed connections if the Singapore to Hong Kong leg is delayed.
