The 777-200LR Worldliner (Longer Range) and 777-300ER (Extended Range) are two long-range airplanes that Boeing has developed to offer airlines additional flexibility in serving the nonstop routes that passengers demand. Launched in February 2000, the two airplanes can fly more passengers farther and faster than the competition, the A340-600 and A340-500.
Factory rollout of the first of the two models, the 777-300ER, took place on November 14, 2002. Flight testing of the 777-300ER began in early 2003, and the first airplane of this model delivered in April 2004 to International Finance Lease Corp., and their customer, Air France.
The first 777-200LR (Longer Range) -- the world's longest range commercial airplane -- was unveiled February 15, 2005. The airplane's first flight took place March 8 and has begun a six-month flight-test program. First delivery is scheduled for January 2006 to Pakistan International Airlines.
