The Story Of Delta’s Short-Lived Boeing 747-400 Operations

After a flight from Seoul (ICN) to Detroit (DTW) on December 19th, 2017, Delta Air Lines retired the last of its Boeing 747s from scheduled revenue service. Despite the 747-400 being used between 2009 and 2017, you might be surprised to learn that Delta Connections Dornier 328JETs had more flights in one year than the 744 did in total.
