Departure Times

Why does flight aware add ten minutes to the departure time. I’ve seen this on several of my own flights as well as other. The departure time flightaware gives is ten minutes later than what I actually file.

Please provide examples of your flights.

We display ETMS estimated departure times rather than filed departure times; they tend to be more accurate.

WN 2984 … 9:55am … 11:30am … Nonstop … 2:35

I noticed this one last week when I had to pick somebody up from this flight.
Scheduled 09:55 departure but FA has it at 10:05.

Gotcha, makes sense.

Another consideration is that we’re using wheels up to wheels down times for departure and duration, while the airline schedules are gate to gate times with some padding added.
