Unsurpassed Reliability. The 777-300ER is the most reliable twin aisle flying today. It has the highest schedule reliability of any twin aisle airplane at 99.5 percent – the airplane is on time, nearly all the time.

The Boeing 777-300ER is widely considered one of the most successful and "best" wide-body aircraft ever built, both from a technical and passenger perspective. Known as the "workhorse" of long-haul travel, it has an exceptional safety record and a dispatch reliability rate of nearly 99.5%, meaning it rarely suffers from mechanical delays. For passengers, it is often favored because its wider fuselage allows for more spacious seating compared to the 787 Dreamliner or A350 when configured in an 8 or 9-abreast layout, though many airlines have unfortunately moved to a narrower 10-abreast "high density" configuration in Economy. It features massive GE90 engines—the most powerful in the world for years—which provide a sense of stability and power during takeoff. While it lacks some of the ultra-modern "jet lag-reducing" features of the 787 (like higher humidity and lower cabin altitude), it remains a favorite for its proven reliability and the sheer "heft" and smooth ride it offers on 12-to-15-hour transoceanic flights.
