The 777-200LR Worldliner is hailed as the world’s longest-range airliner. So, compared to the 300ER, just how much farther can it actually fly? The Boeing official website features a performance comparison of these two models. For instance, the 200LR has a range of 17,395 km, while the 300ER has 14,490 km. The 200LR wins by 2,900 km—truly impressive.

Consequently, the 200LR can operate routes lasting up to 19 hours, such as: New York-Singapore Perth - London New York - Auckland Chicago - Sydney Miami - Taipei It is capable of directly connecting the cities listed above.

In contrast, the 300ER is capable of operating routes lasting approximately 15 hours, such as: Los Angeles - Sydney New York - Hong Kong Singapore - London Paris - Los Angeles Dubai - New York These are typical routes for this model.

Other data includes: Passenger capacity: The 200LR carries 301 passengers, while the 300ER carries 386. It is clear that to achieve range, one must sacrifice passenger count. Maximum Takeoff Weight: The 200LR is 347 tons, while the 300ER is 351 tons. They are basically on par. Length: The 200LR is 63.7 m, while the 300ER is 73.9 m. The 300ER has a clear advantage. However, data for wingspan, height, cabin width, and fuselage diameter are completely identical—not even a centimeter of difference.
