Boeing 767 vs Boeing 777: an in-depth comparison

The 767 and 777 heralded a new age in transatlantic travel, with Boeing adopting new approaches to their design and manufacture. We compare the two twin-engine types to find out how they match up.

Not content with dealing with the complexities of designing and producing one aircraft type at any one time, in the early 1970s Boeing decided to embark on a parallel programme of designing the widebody 767, and narrowbody 757.

The company hoped that the new 767 would appeal to those operators upgrading from the 727 or Lockheed TriStar’s and McDonnell Douglas DC-10s. Internally, it was seen as direct competition to the A300 and A310 from Airbus, which had begun to make inroads into the US market. And with fuel prices rocketing at that time, the main selling point of the new aircraft was fuel efficiency - with Boeing looking for up to 30% cost savings over previous aircraft, through the use of computer-aided design, new engines, and wing technology.
