The Boeing 767 became the most frequently used airliner for transatlantic flights between North America and Europe.
In the mid-1980s, the 767 spearheaded the growth of twinjet flights across the northern Atlantic under extended-range twin-engine operational performance standards (ETOPS) regulations, the FAA's safety rules governing transoceanic flights by aircraft with two engines
Long-haul flights were expanded during the 1930s as Pan American Airways and Imperial Airways competed on transatlantic travel using fleets of flying boats, such as the British Short Empire and the American Boeing 314
