that's not true, 9200ft would be the "normal" condition for operating.
If you want to operate ABV 9200ft (which is completely normal), you have to follow some SPECIAL Ops Procedures, FCOM 2, High Altitude operation.. just a few more things to do in the cockpit...
and also, you said the airports is 10 thousand or so, you do NOT need to takeoff or Land with the OXY Mask on..
