I couldn't find it either. Just people guessing. The FA on my flight this week told me he thought for sure it would be SQ219/220 starting the first week in November but that's impossible to do with just one plane. I told him that but he still insisted he thought it would be those flights. He did say it hasn't been announced officially so we have to wait before we know for sure. I'm betting it'll be SQ221/232. I'm booked on that the first week in November so I'm hoping I've guessed correctly.
