Boeing's next-generation twinjet By the late 2000s, the 777-300ER became the top-selling 777 variant, thanks to its impressive performance: a combination of the -200ER's range and the -300's added capacity. In this period, the 777 topped Boeing's revolutionary 747 as the manufacturer's most profitable jetliner.

In 2026, the Boeing 777-300ER (the "Triple Seven") is widely considered one of the greatest long-haul commercial aircraft ever built. From a passenger perspective, it is "good" because of its spacious cabin architecture, featuring nearly vertical sidewalls that provide more shoulder room in window seats and high ceilings that reduce the feeling of claustrophobia. For airlines, it is a legendary "workhorse" due to its incredible dispatch reliability (over 99%) and the power of its massive GE90 engines. While newer planes like the 787 Dreamliner or Airbus A350 have higher cabin humidity and lower "cabin altitude" (which reduces jet lag), many frequent fliers still prefer the 777 for its stability and the quieter experience in Premium cabins. However, there is a "con" in 2026: many airlines have moved to a 10-abreast (3-4-3) configuration in Economy, which results in slightly narrower seats compared to the original 9-abreast layout. Despite this, its safety record and the sheer comfort of its First and Business class "suites" make it a premier choice for transoceanic travel across the globe.
