I am really pleased to hear that finally the DOT has fined airlines for tarmac delays. Three airlines were fined for overnight delays at Minnesota back in August. The DOT and FAA need to be very strict, they have set precedents with these fines. Not only do tarmac delays disturb the traffic flow at that airport, they also cause a ripple delay effect across the National Airspace System. Airlines must realize the importance of maintaining a tight schedule and some decorum along with it.
