The distances in this section of the hop are rather large, so I imagine that some would want to make these trips in as quick a time as possible.
For the first leg from Honolulu to Johnston Atoll, I used an A340 at 20k ft.
The trip took just over 2 hours to travel the 713nm.
For the second which I completed yesterday, I used the Concorde at full throttle with a full tank of fuel, and completed the 1,256nm trip in just under an hour, with just enough fuel left to taxi to the gate.

The longest of the Pacific hops is now behind me, with the rest averaging around 400nm until I reach Sydney.
I hope to hear from some others flying the hop.
