I think the answer might be quite surprising. Any guesses?
The 777-200LR version is 9400nm but that is at the optimal altitude profile.
Since the qrh doesn’t answer that question:
Assuming 180.000 liters (150 tons) in the tanks I’d say around 2500-3000 NM depending on power setting, a total guesstimate though.
Anything to do with this?

A nice read, anyway.
Curiously my Q had nothing to do with MH370. It was an unfortunate choice of aircraft type 
Interesting read, indeed. I will update the MH370 thread.
All I know is that in something as modest as a Citation in the early part of the flight there is frequently caution “Check fuel at Destination” (which means plan for a glide approach).
It can remain on sometimes until over FL300, but we still land with 1500lbs or more. The burn is over twice as much at 1000 ft vs 40,000 ft, and the TAS is 250 vs 430 in the Citation

Crossing the atlantic I have had it to FL380…..wakes you up.

My gut feeling is roughly 1/4 of max range assuming all “aircraft automatic XYZ deployments” are OFF

Were you expecting more tailwind? or more height?

Please explain for me what you mean?
Performance will still be better than your guesses.
Try a B747-8 and do the math:
So, would the answer be established simply by taking the IAS from the above table? What units is the FF/ENG?
