What is the difference between 777 LR and 777 ER?

Boeing designates aircraft range using ER and LR. ER signifies Extended Range, meaning the plane can fly further than the standard model. LR stands for Long Range, indicating an even greater flight distance capability than the ER version, allowing for longer, non-stop routes.

The 777-200LR (Long Range) is a long-range, wide-body airliner produced by Boeing Commercial Airplanes. It is the first and only variant of the Boeing 777 family to be capable of flying over 10,000 nautical miles (18,520 km) without refueling. The aircraft has a range of 9,380 nautical miles (17,370 km) and can accommodate up to 350 passengers in a three-class configuration.

The 777-200LR was developed in response to the growing demand for non-stop flights between major cities across the globe. The aircraft made its maiden flight in February 2005 and entered service with Pakistan International Airlines in February 2006. Since then, the 777-200LR has been ordered by a number of airlines, including Air India, All Nippon Airways, Cathay Pacific, Emirates, Etihad Airways, and Qatar Airways.

The 777-300ER (Extended Range) is a long-range, wide-body airliner produced by Boeing Commercial Airplanes. It is the third and final variant of the Boeing 777 family to be developed, and it is the largest variant of the family. The aircraft has a range of 7,370 nautical miles (13,650 km) and can accommodate up to 386 passengers in a three-class configuration.

The 777-300ER was developed in response to the growing demand for non-stop flights between major cities in Asia and Europe. The aircraft made its maiden flight in February 2003 and entered service with Air France in April 2004. Since then, the 777-300ER has been ordered by a number of airlines, including Air China, All Nippon Airways, British Airways, Cathay Pacific, Emirates, Etihad Airways, Japan Airlines, Korean Air, Lufthansa, Qantas, and Singapore Airlines.

The 777-200LR and the 777-300ER are both long-range, wide-body airliners that are capable of flying non-stop between major cities across the globe. However, the 777-200LR has a longer range than the 777-300ER, and it can accommodate fewer passengers. The 777-300ER has a shorter range than the 777-200LR, but it can accommodate more passengers.
