Bombardier has formally introduced the Next Generation version of its CRJ700, 900 and 1000 that feature all-new cabins with increased use of composite materials.

"The NextGen aircraft will offer advantages in operating costs versus their nearest competitors, which will have up to 15% higher trip cash operating costs," Bombardier Regional Aircraft President Steve Ridolfi said.

The Canadian manufacturer said NextGen improvements include fuel burn savings up to 4%, lower maintenance costs and longer intervals on maintenance schedules. Cabin windows have been enlarged, increasing the overall viewing area by 24%, and new LED lighting and redesigned sidewall and ceiling panels have been added. Overhead bin space will accommodate a larger roller bag, increasing stowage by nearly 27%.

Northwest Airlines is the launch customer and is taking delivery of a CRJ900 this quarter.
