Delta (DL) #9971 Flight Tracker ? FlightAware
Although an A332, this DL bird flew 18:36 nonstop from Changi to KATL on May 26th. Of course, it was an empty ferry flight. I wondered about the economics of this flight being nonstop, obviously hauling a max fuel load as opposed to stopping somewhere along the route to refuel. Balance between an extra landing fee, an extra couple of hours enroute and the cost of hauling the extra fuel for the first half of the flight.
