Boeing has delivered its first next-generation 737-900ER with the new Boeing Sky interior to Tajikistan-based Somon Air.

The 737-900ER is the newest member of the next-generation 737 aircraft family and is also the highest capacity, longest-range airplane in Boeing’s single-aisle fleet.

The aircraft features new overhead bins, LED lighting, new designs for window reveals and sculpted sidewalls.

The airline said the fuel efficiency and reliability features of the 737-900ER will offer cost savings.
