Now if A/C leaves stand at 0510, it is considered to be “on time”. That’s fine. But if it touches down at say 0620, the arrival on the displays (and nowadays, available on line) is given as “5 minutes early”. Now at somewhere like AMS, the time to taxy in after a landing on 18R might be as much as 15 minutes so the aircraft arrives on the stand 10 minutes behind the scheduled time.
Can you give an example of an airport/airline that you consider to be guilty of this practice?
I ask because if you look at live arrivals info for an airport like Heathrow, for example, you will see a display showing entries like "LANDED 08:32".
That doesn't sound like anyone being dishonest, it's simply a statement of fact.
