Editing Delta Air Lines (section)

===Growth and acquisitions===
By 1970, Delta had an all-jet fleet, and in 1972 it acquired [[Northeast Airlines]]. Trans-Atlantic service began in 1978 with the first nonstop flights from Atlanta to [[London]]. In 1981, Delta launched a [[frequent-flyer program]]. In 1987, it acquired [[Western Airlines]], and that same year Delta began trans-Pacific service (Atlanta to Portland, Oregon, to Tokyo). In 1990, Delta was the first airline in the United States to fly [[McDonnell Douglas MD-11]] jets. In 1991, it acquired substantially all of [[Pan Am]]'s trans-Atlantic routes and the Pan Am Shuttle, rebranded as the [[Delta Shuttle]]. Delta was now the leading airline across the Atlantic.<ref name="journey" /><ref>{{cite web|url=https://www.deltamuseum.org/exhibits/delta-history/timeline/decades/1920|title=Delta Timeline|last=Delta Flight Museum|website=www.deltamuseum.org|url-status=live|archive-url=https://web.archive.org/web/20190414091215/http://www.deltamuseum.org/exhibits/delta-history/timeline/decades/1920|archive-date=April 14, 2019|access-date=October 2, 2019}}</ref>

In 1997, Delta was the first airline to board more than 100 million passengers in a calendar year. Also that year, Delta began an expansion of its international routes into [[Latin America]].<ref>{{cite web | title=1990s-Delta History | url=https://www.deltamuseum.org/exhibits/delta-history/timeline/decades/1990 | publisher=[[Delta Flight Museum]] | access-date=May 13, 2019 | archive-url=https://web.archive.org/web/20190513215208/https://www.deltamuseum.org/exhibits/delta-history/timeline/decades/1990 |archive-date=May 13, 2019 |url-status=live}}</ref> In 2003, the company launched [[Song (airline)|Song]], a [[low-cost carrier]].<ref name=journey/>
