CHICAGO, April 14, 2026, 5:02 PM CDT.
Shares of American Airlines Group surged Tuesday, climbing roughly 8% in late trading after Reuters said United Airlines CEO Scott Kirby brought up the idea of a merger with American during a meeting with President Donald Trump in late February. That’s a big swing for American, which is carrying around $25 billion in long-term debt and lags its bigger competitors in profitability.
The report is significant: a United-American merger would mark the largest U.S. airline deal in over ten years. Looking at 2025 schedules, the merged airline would command close to 40% of domestic seat capacity—about four out of every ten seats planned for U.S. routes. That sort of dominance would instantly put antitrust regulators on alert.
No real clarity coming out of Washington. Transportation Secretary Sean Duffy last week said there’s “room for some mergers,” but according to a Reuters source close to the White House, officials aren’t keen on any moves that might push fares up before the November midterms. Reuters
So far, there’s no indication that formal negotiations are happening. According to Reuters, it’s not clear if United followed up on Kirby’s Feb. 25 proposal to American. Both airlines wouldn’t comment.
This goes a long way toward making sense of the jump. American’s market cap sat near $7.4 billion late Tuesday, compared with United at about $31.2 billion and Delta at $43.4 billion. Seaport analysts pointed out that some of the surge likely came from short covering—traders who’d previously bet against the stock scrambling to buy shares back.
The hurdles are significant. “This seems hopeless to me,” said William Kovacic, head of George Washington University’s competition law center, pointing to major overlaps in markets like Chicago in comments to Reuters. Andre Barlow of DBM Law Group argued that merging United and American would shrink the “Big 4” down to just three major carriers, leaving a single dominant force. TD Cowen analyst Tom Fitzgerald added that, even before any required asset sales, the merged airline would hold at least 50% of domestic capacity at 159 airports. Reuters
American has its balance sheet working for and against it. There’s roughly $25 billion in long-term debt still on the books. Yet, as management pointed out last month, the company ended Q1 with more than $10 billion in liquidity—cash plus funding it can draw—and debt hitting a decade low. “Built for times like this,” Chief Executive Robert Isom said.

The pressure hasn’t eased. Back in January, American assured investors that premium demand and business travel were picking up, but Reuters subsequently reported the airline continued to trail competitors on profits—a shortfall that sheds light on why shares surged Tuesday.
Fuel’s a wildcard, too. American and United have dropped off since late February, Reuters noted, as the U.S.-Israeli conflict with Iran sent jet fuel costs climbing—a margin crimp that can quickly weigh on capacity plans and complicate funding for a major merger.
Legal headwinds aren’t letting up. JetBlue’s attempt to acquire Spirit hit a wall when a federal judge blocked the deal in 2024, and the appeals court decision that shut down American’s old Northeast Alliance with JetBlue stands as a warning: even modest airline partnerships have a tough time surviving antitrust scrutiny.
American, based in Fort Worth, Texas, is set to release its first-quarter numbers on April 23 at 7:30 a.m. CT, as it announced last week. After shares surged Tuesday, that earnings call shapes up as the next big marker for investors.
