Delta Air Lines has ordered 100 Boeing 737-900ERs in a deal which Boeing values at more than $8.5 billion at list prices.

The widely expected order is part of Delta’s fleet-renewal effort to replace its less-efficient domestic aircraft and the Boeing 737-900ER deal specifically is aimed at replacing Delta’s aging domestic fleet of Boeing 757s.


Following its merger with Northwest Airlines, Delta Air Lines operates 163 Boeing 757-200s and 16 Boeing 757-300s, so it is possible that Delta could place additional orders for 737-900ERs at a later date should it wish to replace all the 757s on a one-to-one basis.

“The 737-900ER is the perfect airplane to replace the older, less efficient airplanes in our single-aisle fleet,” Ed Bastian, president of Delta Air Lines, said in a statement. “Reliability and fuel efficiency are direct contributors to our financial performance. The 737-900ER will provide us a reliable airplane with the lowest fuel burn in our domestic fleet.”

On August 25, 2011 Delta Air Lines announced an order for 100 Boeing 737-900ERs in a deal which Boeing valued at more than $8.5 billion at list prices. The order is part of Delta’s fleet-renewal effort to replace its less efficient domestic aircraft and is specifically intended to replace Delta's domestic fleet of Boeing 757s.

Boeing notes that the Boeing 737-900ER is the newest member of the Next-Generation 737 family. It also is the highest-capacity, longest-range aircraft in Boeing’s single-aisle fleet. New aerodynamic and structural-design changes allow the 737-900ER to carry up to 180 passengers in a typical two-class layout.

All of Delta’s 737-900ERs will feature the new Boeing Sky Interior. This new interior introduces new lighting and curving architecture which create a distinctive entryway.

According to Boeing, in aircraft fitted with the Boeing Sky Interior passengers will experience a more open cabin feel and a blue-sky-like environment simulated by light-emitting diode (LED) lighting. The new interior also features sculpted sidewalls and newly improved and expanded pivot bins.

Delta is known to have at least a 200-aircraft domestic narrowbody replacement requirement, which the order for 100 737-900ERs only goes part-way to fulfilling. The airline still has to make a decision on replacing 100 or more 120-to-150-seat aircraft in its massive fleet and Boeing, Airbus and Bombardier are all competing to win Delta’s business.
