This thread alerted me to the schedule change. Thanks OP. We had the UA evening flight and was automatically rebooked on the day flight. The issue was it departs 5 hours before we arrived in HK. Called UA to rebook and agents read off all the dates and times and asked if I was ok with it. I said I can’t time travel 😂. Tried to get in SQ from SIn as that’s where we started no dice, but they put us on UA direct from there. None of the other options were really viable and they wouldn’t even try an open space on *A partner.
