For decades, the Boeing 767 has been one of the defining aircraft of the global air cargo industry. Indeed, the Airbus A330 is increasingly emerging as the aircraft filling the role once dominated almost exclusively by the 767.

While the Boeing 777-8F will undoubtedly attract attention as aviation's next major freighter, the more significant shift may already be underway, with the Airbus A330 quietly becoming the widebody that is replacing the Boeing 767 across cargo networks around the world.
