OTD is pushback or release or a/c brakes, Screens show actual take off times.
Not quite. I recall at BFS a flight was shown as departed as soon as it pushed back i.e. it was "in flight" by the legal definition.
Anecdotally it always seemed that Flybe were mentioned as being delayed more than other airlines on the morning drive to work. There was more than a few occasions when I pitched up at EGAA to see a DH8 or two on the apron implying that they were late in to EGAC.
Just my perception of course.
