Despite Guidance Withdrawal, U.S. Airline Stocks Increased Market Cap by $460 Million in One Day

Alaska Air Group Inc. (NYSE: ALK) closed at $46.25 on the 27th, up 5.62%. Its market capitalization rose by about $300 million in a single day—bringing the total to roughly $5.1 billion (about KRW 7.7 trillion)—on a trading volume of approximately 2.14 million shares.

In the first quarter of 2026, the company reported a net loss of $193 million and a pre-tax margin of –9.6%, and withdrew its full-year guidance due to oil price volatility. At the same time, it is pursuing network expansion and enhanced premium services by planning to acquire Hawaiian Airlines, launch new European routes, and invest in airport lounges.

Headquartered in SeaTac, Washington, Alaska Air Group is an American airline holding company that operates Alaska Airlines, Hawaiian Airlines, and regional carrier Horizon Air, with strong positions on the U.S. West Coast and Hawaiian routes. Through successive acquisitions of Virgin America and Hawaiian Airlines, the group is aiming to evolve from a mid-sized carrier into a global network airline.
