It will be better if Sri Lankan can get four Boeing 777-300ER aircrafts
The Boeing 777-300ER ("ER" for Extended Range) is the B-market version of the −300. It features raked and extended wingtips, a new main landing gear, reinforced nose gear, and extra fuel tanks.
The 777-300ER also has a strengthened fuselage, wings, empennage, and engine attachments. The standard GE90-115B turbofans are the world's most powerful jet engines in service, with a maximum thrust of 115,300 lbf (513 kN). The maximum range is 7,930 nautical miles (14,690 km), made possible due to a higher MTOW along with the increased fuel capacity.
The 777-300ER can fly approximately 34 percent farther than the −300 with a full load of passengers and cargo. Following flight testing, the implementation of engine, wing, and weight modifications produced an added 1.4 percent reduction in fuel consumption.
Benefits
Using only two engines produces a typical operating cost advantage of around 8–9 percent for the 777-300ER over the A340-600.
The 777-300ER’s direct Airbus competitor is the A340-600.
As of 2011, 777-300 deliveries to 24 different customers totaled 272, with 220 unfilled orders. Operators had 237 aircraft in active service.
