ULH one stop

I was wondering about ULH distances - or maybe UULH - as a side note to MEL-LHR idea from Qantas.

If you can't reach destination direct, you will usually do the trip (as a passenger) with one stop. From a passenger perspective, the preferences would not be clear, as some prefer to have a longer sleep on one leg, and therefore shorter second trip. Others would say 50-50 is better, not to sit in one plane THAT long.

What I wonder about, is there any preference from airlines involved, other than having mid-airport able to feed both sections? If we expand on this MEL-LHR, I guess more people would be travelling on sections (eg. LHR-SIN, be it O&D, or other destinations), and this is probably more important. But what other factions could play? Crews time of work, likely. Ability to do full rotation, likely. Offset from optimum route, sure, however this will be decided by passengers rather (time). Fuel? Not so much on a given distance, I guess, over complete distance it would be neglible.

Any other considerations that airlines would find worth analyzing?

Cheers,
Adam

Airlines prefer whichever options gives them a higher profit. ;)

This would depend on the route. For QF, for example, they have a customer base for MEL-LHR. There are lots of costs involved in stopping in the form of airport fees, ground staff, etc.

Fuel burn increase is not negligible with non-stop over one stop. Fuel burn increases geometrically with increased distance. If your uplift is 120 tonnes of fuel, you're burning tonnes an hour just carrying it in the first few hours of flight.

Plus the aircraft is used ~2 hours more per trip, if the route is flown by a specialised type you may need to buy one more.

The cost of an extra two hours are probably lower than an extra landing gear cycle. But certainly the specialised type is a consideration. :)

If the direct route goes over a lot of water, that will obviously set a limitation. Turnarounds need to be quick and smooth, so some airports and even countries will be avoided like the plague. I'd imagine having a partner airline at the stopover point would sway the decision somewhat, like Qantas did in Dubai. On and offloading passengers at the stopover could also be attractive, hence the number of airlines that stopped in Singapore in the past.
