The same year also provided a new image for Delta as it redesigned its logo to what is present today. In 1970, Delta became an all jet airliner. The airline continued buying out its competitors and this time it was North East airline that was purchased in the year 1972. The great reign of Delta Airlines reached another milestone in the year 1975 when the launched the first airline called Delta Air Express which guaranteed air express service with high priority and guaranteed cargo services. As the deregulation act came into place, Delta launched its first transatlantic flight from Atlanta to London under the leadership of the new CEO David Garrett which followed another expansion to Frankfurt the following year. In 1979, Delta celebrated its 50th year of service with flights to Frankfurt and it became the first airline to board one million passengers in one city in one month.
In addition to the above achievements, the 1980's brought mixed feelings at the company. With the development of computers, Delta managed to begin computer based reservation systems and launch its first frequent flyer program. But the airline suffered losses in the year 1982.Employees then took payroll deductions to raise about $30 million to purchase the company's first Boeing 767 which was named "The Spirit of Delta,"" in 1982. Between the year of 1984-1987, Delta merged with several regionals and partnered with some to increase its services to Hawaii. It also became the fourth largest carrier in the U.S and fifth in the world with its services to Portland, Oregon and Tokyo in 1987 under the new chairman and CEO; Ronald Allen. The airline expanded its operations to Asia in 1988. As Delta Airlines continued soar higher, the year 1991 was no different. The airline purchased all of Pan-Am's Trans-Atlantic routes and shuttles hence making it the largest acquisition of flights in airline history and also making Delta a global carrier.
