The Boeing 737 in 2003 remained the company's best-selling commercial airplane, propelled by strong demand from the world's low-cost airlines.
The Next-Generation 737 models (737-600/-700/-800/-900) accounted for 86 percent of the 239 Boeing commercial airplanes ordered last year.
The Next-Generation 737s have annually been Boeing's best seller since entering service in 1998.
The Next-Generation 737s are the newest and most technologically advanced in their class, offering new flight-deck technologies such as Head-Up and Vertical Situation displays that aren't available on competing Airbus models.
In addition, the modern 737s provide exceptional economics through lower fuel burn and maintenance costs.-PR
