Late again? Then you must be on Delta Comair Flight 5610 from BWI to JFK. According to the Department of Transportation's July report, this flight is late more than 96% of the time. How late? Nearly two hours on average. It's not BWI's fault (they didn't have any other flights listed on the Top 25 chronically late list) - it's JFK. New York airports were among the most tardy. Among the Top 10 latest flights, all of them were Delta affiliates. I vote for Delta to go stand in the corner.
