O'Hare International has reclaimed its distinction as the world's busiest airport, according to statistics that show it logged more traffic last year than Atlanta's Hartsfield International.

O'Hare served 58.9 million passengers, while Atlanta handled 45.9 million, according to the statistics from the Chicago Department of Aviation, and the Chicago airport logged a record 803,453 departures and landings, to Hartsfield's 778,779.John Braden, a Hartsfield spokesman, said a major reason for the drop in traffic there was a decline in discounted fares and service cuts by Eastern Airlines, a big Atlanta tenant.
