The GEnx-1B engine designed for the 787-8 can churn out 64,000 pounds of thrust. "It's usually one of the last tests that we run to make sure all of the airplane systems are working," said Ron Stephens who is on the propulsion team for the Boeing 787 Dreamliner. "We verify that the (1) system starts, motors, provides all of the cockpit displays and shuts down properly." This test comes after years of (2) and development by Boeing and GE. Like the 787, the GEnx takes the use of composites to a new level. Both the fan blades and (3) casing are made with the strong and durable but light weight (4). The reduction in (5) is a major reason why GE says the GEnx-1B will burn 15% less (6). The power plant will also be significantly (7) and cleaner and easier to maintain than its predecessor.

Базовой моделью серии Classic являлся самолет Boeing 737-300, также выпускались укороченная версия с увеличенной дальностью полета Boeing 737-500 и версия с удлиненным фюзеляжем Boeing 737-400. С 1997 г. в авиакомпании поставляются самолеты серии Boeing 737 NG (Next Generation), оснащенные более экономичными современными двигателями, новым увеличенным крылом с возможностью установки аэродинамических законцовок (winglet), а также новым оборудованием салонов. Самолеты нового поколения имеют более высокие скорость, дальность и экономическую эффективность по сравнению с предыдущими моделями. Boeing 737 NG производятся и в настоящее время и наряду с самолетами семейства Airbus A320 являются основными среднемагистральными лайнерами авиакомпаний по всему миру.
