Narrative:
A revision was made to our aircraft operating manual, but no revision was sent to dispatch. The revision changed the maximum altitude from FL370 to FL360. For a change of a basic operating rule like this, we need to be personally notified, as well as the manual revision. Over the last months, I have filed many flts at FL370, most notably the dlh-ord flts.
