Final answer:
Federal Express acquired Tiger International Inc. in 1989, and the integration of the Flying Tigers network on August 7, 1989, made it the world's largest full-service, all-cargo airline, following changes in the industry due to the Airline Deregulation Act of 1978.
Step-by-step explanation:
The acquisition of Tiger International Inc. by Federal Express (now known as FedEx Corporation) signifies an important event in aviation history. The purchase took place in 1989. When Federal Express integrated the Flying Tigers network on August 7, 1989, it became the world's largest full-service, all-cargo airline.
This growth was an outcome of industry changes following the Airline Deregulation Act of 1978, which allowed market forces to determine airfares and schedules, influencing the rise and fall of many airlines. Federal Express, with its strategic acquisition, capitalized on the opportunity created by deregulation, enhancing its operational reach and fleet capacity to serve a global audience. As a result, its robust international presence transformed the logistics and express transportation sector significantly, setting a new standard for air cargo services worldwide.
