We are the only Express carrier in the system that uses wheel movement to trigger our out time. Everybody else is door/brake/beacon or some combination or (until recently) didn't have ACARS and would just call whatever they wanted. Every few months we get an angry letter from management about how we are way behind in D:0 departures compared to everybody else.
Duh.
Apparently you weren't advocating or speaking from experience but rather just sayin'?
