Somebody at the WSJ has a sly sense of humor:
FAA Restrictions To End at O'HareMeanwhile.... "...O’Hare, only 70.4% of flights arrived on time this April , placing it 30 out of 32 of the nation’s largest airports."
CHICAGO -- The Federal Aviation Administration said it will lift flight caps at O'Hare International Airport this fall, to coincide with the extension of an existing runway and the completion of a new runway at Chicago's largest airport... based on winter schedule requests, the airlines collectively want to add about three departures per hour. That should result in a modest decrease in delayed flights.
O'Hare is the bane of any consultant; they spend $15 billion, and the result is a "modest" decrease in delays.
