Reading the new report here from CNN.....I know take it with a grain. So now the reports indicate the flight climbed to FL450, descended to FL230, then up to FL300 (or something like that).
Just out of curiosity, for those that fly the 777, what is the max altitude that can be pre-selected on the FCP ALT window (I.e. If someone were to just "spin it up"?

I suspect something similar here.

Thought this was a little funny, but very wrong.

It's beginning to sound like the person in the cockpit knew what he was doing.

Descent to lower altitude, engage autopilot, sit back and wait for fuel to run out.

Unfortunately this make sense and there are no big loopholes.
I couldn't see one pilot locking the other out and then taking the airplane on an hours-long excursion...with a pilot and 100 ABPs they would eventually have gotten back into the cockpit. But dumping the cabin would limit mobility in the cabin and eventually they would run out of O2.

One problem-- the limit switches on the outflow valves will limit the cabin to about 14,000' by going fully closed, then the leak rate of the plane and whether the packs are turned off will determine the ultimate cabin altitude. Yes, it would eventually reach the plane's altitude, but it would take long enough that a "cabin riot" could be mounted.
One pilot taking out the other with a crash axe is more likely. Turn off both packs at F450 in a Global and the cabin only rises at about 1,000 fpm. The outflow valves almost immediately go closed trying to maintain the cabin altitude.
