United Airlines was fined $1.1 million by the Department of Transportation (DOT) for delaying passengers on ground (not letting them out) for more than the set maximum 3-hour limit.

On July 13, 2013, 939 passengers were on board of these flights that exceeded the time limit. Two of the affected airplanes didn’t have working lavatories.
Part of the fine will go to the affected passengers, part to the DOT and United will use $440K to purchase a system to track planes on the ground at the O’Hare airport.
United was fined by the DOT in August for $350K for failing to issue passenger refund in a timely manner (read more here).
The amount of the fine is rather insignificant considering the size of the airline and 40% of the amount is used to purchase a plane tracking system to ensure that these mishaps would be less likely to happen in the future.
