Schedule change question
Next August I am booked via SQ to fly ADL-MEL (on VA), MEL-WLG (on SQ) and WLG-DUD (on NZ), all on the same ticket. The VA flight departs ~7pm and I will overnight in MEL and fly the MEL-WLG the following morning. There has been a schedule change for the SQ flight, it now leaves 10min earlier at 0650....I am wondering how flexible SQ are with schedule changes and if SQ would re-route me on NZ for the trans-tasman leg (so I could depart later and get a sleep in! not that I would say that of course) or depart the following day from ADL and fly ADL-BNE-DUD on VA. Thanks in advance!
