Can anyone provide what the typical cruise altitude for the 777-200ER is? I believe that max certiifed ceiling is 43K, but above 40K you need one crew member on ox at all times.

If they are on the first few hours of the journey they tend to stay at the low FL300s and after burning off some fuel it could be somewhere close to FL400.

Yes, the max certified pressure altitude is 43,100ft, but I don't know where you get the oxygen bit from. There are no crew oxygen usage requirements above 40,000ft (on British registered 777s).
Our only limitation is, if the crew oxygen system is unserviceable, then the max ceiling is FL400, and then, above FL350, the handling pilot must use a portable oxygen set.

In general, I would agree with this statement, but we seem to be able to get up to and above FL350 before most other 'heavies' at an equivalent % weight.

Mine was just a general statement, however can you explain why your airline can get up to and above FL350 before most other 'heavies' at an equivalent % weight? Or are you refering to the 777 in general?
