United Airlines CEO Scott Kirby quietly approached his Delta Air Lines counterpart last year about combining the two carriers into a single airline giant, but Delta evaluated the idea and walked away, leaving Kirby without a dance partner after American Airlines also rejected him.
Kirby contacted Delta CEO Ed Bastian to pitch the potential tie-up, Fox Business reported, citing a Wall Street Journal account based on people familiar with the matter. Delta's leadership discussed the proposal and conducted what the Journal described as "preliminary due diligence," weighing potential benefits before deciding not to move forward. Both airlines moved on.
Neither carrier wanted to talk about it publicly. A United spokesperson said the company had "nothing to share." Delta declined to comment altogether. But the disclosure reveals that the CEO of one of America's largest airlines spent the better part of a year shopping for a mega-merger, and struck out twice.
Before approaching Delta, Kirby reportedly explored a merger with American Airlines earlier this year. American's CEO, Robert Isom, rejected the proposal and criticized the idea as "anticompetitive," according to the Journal's reporting.
That rebuke did not stop Kirby from trying the same play with a different carrier. The approach to Delta came after the American rejection, though the precise sequence and timing remain unclear, the Journal used only relative time references for both overtures.
A merger between United and Delta would have combined two of the nation's largest airlines and reshaped the domestic aviation market. The Journal noted that such a deal would have likely faced scrutiny from federal antitrust regulators and state attorneys general, a significant hurdle even in a more business-friendly regulatory climate.
United has been reconfiguring its fleet and cabin layout to squeeze more revenue from premium travelers, and Kirby has spoken publicly about expanding United's global reach. A merger would have been the fastest route to that goal. Instead, he got two rejections and a public scolding from a rival CEO.
Last month, Kirby appeared at the International Air Transport Association's annual meeting in Rio de Janeiro and offered remarks that now read differently in light of the Journal's reporting.
"I think consolidation is unlikely for United. That doesn't mean we won't still be in the market to buy assets, but consolidation is a low probability."
He told Reuters that United remained open to purchasing airport slots, gates, and other assets, the kind of incremental deals that don't require antitrust clearance or a willing merger partner. That framing positioned Kirby as a pragmatist rather than an executive who had just been turned down by two competitors in succession.
Kirby's pivot toward smaller asset acquisitions tracks with his recent public statements ruling out large-scale consolidation. Whether the shift reflects genuine strategic recalibration or simply the reality that no major carrier wants to merge with United is an open question.
Delta's response to the pitch is worth noting for what it was not. Bastian's team did not dismiss the idea outright. They discussed it internally, ran preliminary due diligence, and then decided the deal was not worth pursuing. That is a measured, corporate-board response, evaluate, decline, move on.
Delta has positioned itself as the premium domestic carrier, with strong margins and a loyal customer base. Folding into a combined entity with United, an airline that has drawn legal challenges over its seating practices and faced operational scrutiny, may not have looked like an upgrade from Delta's perspective.
The stock market, for its part, did not punish either airline for the disclosure. United Airlines Holdings traded at $118.27, up 2.54 percent, while Delta shares sat at $86.67, up 1.89 percent, at the time the report surfaced.
The reporting, while significant, is thin on operational detail. What terms did Kirby propose? What structure, a merger of equals, an acquisition, a holding-company model? None of that appeared in the Journal's account. Nor did any explanation of why, specifically, Delta's leadership concluded the deal was not worth pursuing.
It is also unclear which individuals beyond Bastian participated in Delta's due-diligence discussions. The Journal attributed its information to "people familiar with the matter," a sourcing standard that leaves room for spin from either side.
United has been busy on other fronts as well, from ratifying a new flight attendant contract with 31 percent pay raises to updating passenger conduct policies. Whether the merger push was a serious strategic priority or an opportunistic phone call from a CEO testing the waters is something only Kirby and Bastian know for certain.
The airline industry has not seen a major domestic merger since American Airlines and US Airways combined in 2013. Regulatory barriers, operational complexity, and political risk have kept the big three, United, Delta, and American, in separate lanes for more than a decade. Kirby's double rejection suggests that the carriers themselves may not be eager to change that, regardless of what Washington might allow.
United has also drawn attention for tightening its passenger rules in recent months, a sign that the airline is focused on the customer experience even as its CEO explored a corporate overhaul behind the scenes.
When the biggest airline in the country goes looking for a merger partner and gets told no, twice, that tells you something about the deal, not the market. Sometimes the answer is just no.
