I have been monitoring the departure times of a flight ( AS #208) for several days now that we are taking tomorrow. ( I know...too much time on my hands) Today for instance the web site is showing that the flight left at 8:55... about fifteen minutes late. But when I do the flight tracker feature it shows that it left at 9:45...over an hour late....what is considered the departure time shown on the website? When they leave the gate or the ground.....just curious....
