SQ arrives in INternational terminal while AC leaves Terminal 3. Will I need to go in and out? Can I go directly to lounge then go to AC gate? How many security checkpoints?
My experience is SQ won't let you in even if you arrived with them (even in F), they will redirect you, YMMV.
Also, unless you are a US citizen or have GOES, it can be a long wait at Immigration, so I usually find I don't have a ton of time.
