Airline Stocks Surge by 4 Trillion Won in a Day: Investor Sentiment Heats Up Again

Delta Air Lines Inc. (NYSE: DAL) shares jumped 6.01% on the New York Stock Exchange, closing at $66.99.
That rally added roughly $2.8 billion to its market capitalization, bringing it to about $43.7 billion.

At the AEA International Convention held today in Dallas, Delta—together with Emirates and Singapore Airlines—unveiled new connectivity strategies aimed at boosting European tourism, signaling plans to expand its long-haul network. Delta has also moved to mitigate operational-disruption risks by issuing an emergency travel waiver for passengers facing record-breaking TSA wait times at Atlanta’s Hartsfield-Jackson International Airport.

Headquartered in Atlanta, Delta Air Lines is one of the largest U.S. carriers and a leading legacy airline connecting North America, Europe and Asia through an extensive hub network and a fleet of hundreds of aircraft. In 2025, the airline generated approximately $58.3 billion in revenue and maintained solid profitability. It is now accelerating fleet modernization and route restructuring, with a medium- to long-term goal of producing several billion dollars of annual free cash flow.
