At FL350, Mach .92 (614mph, 533 kn, 988kmph). Voluntairly (don't know why an airline would be pushing her that fast) exceed that and I think you'd do a lot of damage that your airline wouldn't like and your CEO could say that the nearest unemployment line is that way (points north).

So which speed would you suggest on a long flight from klas to honolulu 300 knots or so which would you choose on a long flight ?

It can depend on the cost index, payload, weather, and route. I use 100 when I want to use CI. I haven't been in the 744 for a while so I can't remember what mach that comes out. However, the average cruise speed for the 744 is Mach .85 (567mph, 493kn, 912kmph). I try to keep her below that speed.
