I intend to book LAX - NRT - SIN in SQ J for a December 2024 trip. Ideally I'd like to do it through Aeroplan for the lower miles cost, but for the past few weeks I've been searching this route on Aeroplan and I've only seen the direct LAX - SIN flight come up. My question is, is this route ever available on AP or is it only the non-stop route that is made available?
