What happened with Delta and CrowdStrike in 2024?
In July 2024, a faulty software update from cybersecurity firm CrowdStrike caused a global IT outage that severely disrupted Delta's operations, resulting in approximately 7,000 canceled flights and an estimated $500 million in losses. Delta subsequently filed a lawsuit against CrowdStrike seeking damages.

Delta Air Lines traces its origins to 1924, when Huff Daland Dusters was established in Macon, Georgia, as a crop dusting service. In 1928, C.E. Woolman and a group of investors purchased the company and renamed it Delta Air Service, after the Mississippi Delta region where it operated. The airline began passenger service in 1929, operating a route between Dallas, Texas, and Jackson, Mississippi.

Delta grew steadily through the 1930s and 1940s, expanding its route network across the southeastern United States. The airline was incorporated as Delta Air Lines in 1945 and became a publicly traded company. Delta was among the first airlines to operate the Douglas DC-3, which became the workhorse of commercial aviation in the late 1930s and 1940s.

In the 1950s and 1960s, Delta expanded nationally and internationally, introducing jet service in 1959 with the Douglas DC-8. The airline merged with Chicago and Southern Air Lines in 1953 and Northeast Airlines in 1972, significantly expanding its route network. Delta became one of the major U.S. trunk carriers, competing with American, United, and Eastern Airlines.

Delta acquired Western Airlines in 1987, adding routes in the western United States and expanding its presence in the Pacific. The acquisition made Delta one of the largest U.S. airlines and established its position as a truly national carrier.

The airline industry faced severe disruption following the September 11, 2001 terrorist attacks. Delta, like most major U.S. airlines, struggled financially in the years following the attacks. The airline filed for Chapter 11 bankruptcy protection in September 2005, citing high fuel costs, labor costs, and competition from low-cost carriers.

Delta emerged from bankruptcy in April 2007 with a restructured balance sheet and lower cost structure. Shortly after emerging from bankruptcy, Delta announced a merger with Northwest Airlines, which was completed in October 2008. The Delta-Northwest merger created the world's largest airline at the time, combining Delta's strengths in the southeastern United States and transatlantic routes with Northwest's strengths in the upper Midwest and transpacific routes.

Richard Anderson served as CEO from 2007 to 2016, leading the airline through its bankruptcy emergence, the Northwest merger, and a period of strong profitability. Ed Bastian became CEO in May 2016 and has continued Delta's focus on premium service, operational reliability, and financial discipline.

Delta has made strategic investments in airline partners to strengthen its global network. The company holds a 49 percent stake in Virgin Atlantic, a significant stake in LATAM Airlines Group (South America's largest airline), and a stake in Aeromexico. These investments provide Delta with preferred partner relationships and revenue sharing on key international routes.

In FY2025, Delta celebrated its centennial year, marking 100 years since the founding of Huff Daland Dusters in 1924. The company reported record free cash flow of $4.6 billion and shared $1.3 billion in profit sharing with employees.

Delta Air Lines has established comprehensive sustainability initiatives focused on decarbonization, sustainable aviation fuel, and environmental responsibility, with a commitment to achieving net-zero emissions by 2050. The airline's sustainability strategy is organized around three key areas: what the airline flies (fleet technology), how it flies (operational efficiency), and the fuel it uses (sustainable aviation fuel).

In fleet technology, Delta partners with revolutionary aircraft developers through its Sustainable Skies Lab. The airline announced partnerships with JetZero to develop blended wing-body aircraft expected to be up to 50 percent more fuel efficient, and with Maeve Aerospace for hybrid electric regional aircraft that could reduce fuel consumption by up to 40 percent. Delta continues its fleet renewal program, taking delivery of more than 35 aircraft in 2025 that are on average 25 percent more fuel efficient per seat mile than aircraft retired since 2019.

For operational efficiency, Delta's cross-enterprise Carbon Council works with operating divisions to implement fuel-saving measures including weight reduction, Auxiliary Power Unit usage tracking, optimized routing, new landing procedures, and drag reduction technology. In 2025, Delta exceeded its near-term fuel savings goal, delivering over 55 million gallons of jet fuel savings from operational improvements, representing more than $125 million in annual cost savings.

Delta is significantly increasing its sustainable aviation fuel (SAF) usage, with a 50 percent increase in 2025 compared to 2024. The airline collaborated with Shell Aviation, Montana Renewables, and the Port of Portland for the first commercial-scale SAF uplift at Portland International Airport.

In customer experience sustainability, Delta eliminated single-use plastics by rolling out new paper cups across its entire operation, replacing approximately 7 million pounds of plastic annually. The airline opened sustainable lounges at Seattle-Tacoma International featuring smart windows, all-electric energy with motion-sensing lights, and reusable dinnerware.

Delta maintains strong ethical standards through its people-first culture and profit sharing program. In 2025, Delta shared $1.3 billion in profit sharing with employees worldwide. The company ranked No. 15 on Fortune's 100 Best Companies to Work For in 2025, jumping from No. 94 the previous year, and ranked No. 2 on Forbes World's Best Employers.

Delta, like all major U.S. airlines, operates under extensive federal regulation by the Federal Aviation Administration (FAA), the Department of Transportation (DOT), and other agencies. The airline industry is subject to safety regulations, consumer protection rules, and environmental requirements.

In July 2024, a global IT outage caused by a faulty software update from cybersecurity firm CrowdStrike disrupted operations across many industries, but Delta was particularly severely affected, canceling approximately 7,000 flights over several days. The disruption cost Delta an estimated $500 million. Delta subsequently filed a lawsuit against CrowdStrike seeking damages, alleging that the company's negligence caused significant harm to Delta's operations and reputation.

Delta has faced scrutiny over its SkyMiles program, with some customers and consumer advocates arguing that the program has become less valuable over time as Delta has made it harder to earn and redeem miles. Changes to elite status qualification requirements and award pricing have generated customer pushback.

The airline also faces ongoing environmental scrutiny as one of the largest emitters of carbon emissions in the aviation sector. While Delta has committed to net-zero emissions by 2050 and is investing in sustainable aviation fuel and fleet modernization, environmental groups have called for more aggressive near-term targets.
