Featured Map: Delta's 777 Flying
Delta Air Lines flies two different types of Boeing 777-200. The 18 aircraft share a common cabin configuration:
The specifications and capabilities of the aircraft are quite different, though:
|777-232ER||656,000||430,000||7,423||RR Trent 892||9 in 1999, 1 in 2002|
|777-232LR||766,000||461,000||9,016||GE GE90-110B1||10 in 2008-2010|
Delta also uses the 777-200LR on their third-longest 777 route, from Los Angeles to Sydney. United uses the 777-200ER on this route, with exactly the same number of seats though different engines. Delta may use the 777-200LR to gain greater belly-cargo lift, or simply because there are enough shorter missions to fully use Delta's 777-200ER fleet.
Curiously, Delta's shortest 777 mission at just 971 nm, from Tokyo to Shanghai, also uses the 777-200LR. This peculiarity can be explained by two observations. First, all seven of Delta's NRT arrivals are schedule to arrive between about 2:45 pm and 3:25 pm, with the departing bank between 4:25 pm and 5:30 pm. This schedule has NRT-LAX arriving late morning, with the return departing a bit after noon. Second, LAX-SYD departs 11.5 hours after the arrival of the NRT-LAX flight, which would result in an excessive dwell time if the same aircraft were used for both flights. By instead using the 777-200LR to fly NRT-PVG-LAX Delta gets better utilization of the airframe, and may benefit a bit from greater cargo lift out of PVG.
The 777-200ER flying is much simpler: all out-and-back from NRT except for one, the flight from New York to Tel Aviv. The schedule has one aircraft on the ground at Minneapolis-St. Paul for over 23 hours but this time is likely used for routine maintenance such as an A check. Other than these two trips all of the 777-200ER round-trips from Tokyo are short enough to be accomplished within the ~22 hours between banks.
