To many aviation enthusiasts and travelers, the Boeing 767 conjures up images of classic widebody aircraft operating a variety of routes, from transcontinental flights across the US to long-haul transoceanic routes. First entering service in the early 1980s, the 767 has enjoyed a remarkably long commercial life, and even as newer, more fuel-efficient aircraft have entered the market, the aircraft remains stubbornly relevant, thanks to its versatility and economics.
