Boeing and Lion Air, Indonesia’s largest private airline, are celebrating the delivery of the 50th Next-Generation 737-900ER (Extended Range) to the carrier.

“This is a major milestone for Lion Air and Boeing,” said Lion Air president director Rusdi Kirana.

“We have operated the 737-900ER since 2007 and that airplane has allowed us to grow because of the low operating cost and comfort for our passengers.”

The newest member of Lion Air’s fleet is equipped with the new Boeing Sky Interior.

Passengers will enjoy a greater sense of spaciousness in the cabin in an environment enhanced by light-emitting diode (LED) lighting.

The new interior also comes with decorative sculpted sidewalls, newly improved and expanded pivot stowage bins.

The airplane features a special Lion Air paint design to commemorate the 50th 737-900ER delivery to the airline.

“The success of Lion Air is truly amazing,” said Jim Albaugh, president and chief executive of Boeing Commercial Airplanes.

“I want to congratulate them on this special delivery and look forward to our continued partnership.

Lion Air is the launch customer for the 737-900ER and the largest customer and operator of this airplane in the world.

Lion Air Group operates extensive route network in Indonesia with 488 daily flight frequencies across 71 destinations.

“Lion Air is a leading airline in south-east Asia and changed air travel in Indonesia,” said John Wojick, vice president of Asia Pacific Sales, Boeing Commercial Airplanes.

“We thank Lion Air for their confidence in the 737-900ER.”
