Most delayed flights in America: SFO makes the list!

The US Department of Transportation released its monthly on-time statistics report this week, and September 07' wasn't so bad. While Nationwide statistics showed overall improvement for on-time performance compared to August 2007 and the September 2006, there were 5 flight routes that reported being late more than 85% of the time. One of those "top 5" is a flight that departs San Francisco. DOT considers a plane late when it arrives at its destination 15 minutes or more after the scheduled time.

(Thanks Tommy) U.S Department of Transportation numbers show that airline on-time performance for the month of August was 71.7%.

More than 1 in 4 flights, on average, were delayed more than 15 minutes. Of the largest U.S carriers, United ranked the worst with only 66.2% of their planes arriving at the scheduled time.

August numbers, which are best described as "terrible", are slightly better than the month of July at 69.8% - one of the worst since the government started keeping records in 1995.
