The Best of Times, the Worst of Times May 1999

O'Hare ranked a mediocre 14th last year among 29 major U.S. airports in on-time arrivals and a sorry 23rd in on-time departures. Your chances of coming or going without a delay are best first thing in the morning, and they generally deteriorate as the day progresses
