Sorry..
Meanwhile from the very first para of the Guardian article..
Plane journeys are taking longer than a decade ago, according to a report that claims the change is down to airlines “padding” their schedules to create the impression passengers were reaching their destinations on time.
...but if the airlines get the correction block times correct and then change the advertised arrival time then passengers actually
are reaching their destinations on time.....
(don’s tin hat and looks for another thread to retire to)....
