Qantas' Schedule Change Fails MCT at SYD

[oz_mark]

It effectively leaves ADL at 6:30am Sydney time.

The carrier is really stretching the limits with QF730 - the scheduled 110 minute time for that 725 mile flight gives an average speed of 400Mph, a little more than the 310Mph of the 85 minutes for most MEL-SYD 439 mile flights.

More of a tail wind on the ADL-SYD than MEL-SYD.
SYD-ADL is a slower flight

If I take the same ground times off QF730 I get a average air ground speeds of 460 to 490Mph

Looking at flight aware the flight seems to leave around 5 minutes early each day, around 5.55am.

Even with a couple of loops holding outside Sydney the wheels-up to down is around 1hr45, sometimes a few minutes longer.

It arrives in time about half the time!

That's gate departure - i'm sure the takeoff roll does not commence before 6am.

And the T3 arrival gates tend to be near gate 15.

It is gate departure. I gave flight times for wheels-up to wheels down.

But the good thing is that the flight does seem to be getting underway early if possible. Even leaving the gate five minutes early means better chances of making connections in SYD.

I think the flight out of HBA has near exact same characteristics as flight of ADL:

• Aircraft overnights
• Environmental issues are minimal, especially given it is a takeoff not landing (e.g. can take off in worse vis than land in)
• Having been on this flight many times, on time performance is often dictated by predicted conditions in SYD, which ADL would be the same for
• A220 or 737 that will always have an airbridge at T3
• All the ground circumstances at SYD are the same for both

Could availability of spare crew if cover is needed (more likely in ADL than HBA) also be a factor?

I believe there is a crew base in Hobart, there definitely is for cabin crew, less sure about pilots

It was pilots that I wasn't sure about either...

To close the loop on this one, changed flight to the afternoon before.

First attempt via messenger, claimed couldnt help as rewards seat and needed to call up.

Called up, wholly unhelpful and said couldnt change as it was booked as a 'through ticket' and offered to move both flights to August...

Tried messenger again a few days later and finally sorted, solved in 3 messages back and forward.

Should have mentioned this, this was in the most recent messenger convo from QF Agent where the issue was resolved:

"The minimum connection time in Sydney for this route would be 1 hour so you would have enough time to connect onto your international flight"

But I dont see how that is the case, based on the MCT details provided by @serfty earlier on, quoted below. Either way they did change it free of charge

I believe to read MCT, one first ignores the ONLINE/OFFLINE content then read down the list until a match occurs.

In the case of QF588 to QF63 the first match is this line:

QF-QF DI 1.30 TRM 3 - 1

Yep thats how I interpreted it
