QF2's SIN-SYD 1915 departure has been pushed back to 1950 for Sat 30/03, 35 minutes late. Hoping it can be made up in air as I have a fairly tight domestic connection at SYD (silly, I know).
33kft, isn't your biggest battle upon arriving in Sydney how many other aircraft have landed recently, and hence how long the queues (not so much for SmartGates) for the post-baggage pickup handing over of the incoming passenger declaration form and SmartGate receipt are?
The QF minimum international to domestic connecting time is 75 minutes. I don't recall having managed to do it as quickly, and whatever airline, I usually allow 2.5 hours between such flights in Sydney. That chews up time. Some like you may be in far more of a hurry than I ever am.
Out of interest, what connecting flight and to where are you booked on? If you miss it, what time is the next one?
QF2 into SYD this morning arrived (at gate) at 0720 hours, 65 late after pushing back 86 late in SIN last night at 2041 hours. It's rare for two of the same flight number to be identical: taxiing times at each end, particularly departing, vary as do weather conditions. That said, on many occasions on a gate-to-gate basis this particular flight picks up time. It's arriving at 'peak hour' for international flights coming in.
Today's QF2 is showing as arriving at 1825 hours, 40 late so it will need most things to go right to enable pushback as you suggest at 1950, 35 minutes behind. Not impossible, but all it needs is for one or more passengers (with checked in luggage) to spend too long browsing in the Changi retail offerings (or at AFFer JohnPhelan's 'barrrrr' as per his famous, apt comment) and your task is more difficult tomorrow morning. But let's not be defeatist.
Please let us know how you go: time yourself from walking off the aircraft, to exiting customs, to being at the gate of the domestic flight. This info will be very handy for others, even if the experience differs every time.
