Delta Air Lines was in the news recently after announcing its plans to resume the operation of its longest US domestic flight. Linking Boston Logan International Airport (BOS) in the federal state of Massachusetts with Honolulu International Airport (HNL) in Hawaii, the corridor in question is a whopping 5,095 miles (8,200 km) long. Indeed, such is the sheer length of this route that its distance exceeds many transatlantic services.
