From the Lion Air website:
With the latest addition of the Boeing 737-900ER into Lion Air’s fleet, it will enable the airline to offer more non-stop flights with affordable fares to more destinations.
The newest member of the Next Generation B737 family, this is the most advanced single aisle commercial airplane in the world. It carries up to 213 passengers in a single-class configuration and it weighs 9,550 pounds (4,340kg)......
Wow!
They must have even used composites for the gear if they got the weight down that low!
