Spirit Airlines ceased operations early Saturday, ending a 34-year run as America's largest ultra-low-cost carrier, and within hours, critics from Capitol Hill to Wall Street were pointing the finger squarely at Sen. Elizabeth Warren.
The Massachusetts Democrat had lobbied the Biden administration to block a planned $3.8 billion JetBlue acquisition of Spirit, co-signed a letter pressuring the Department of Transportation to resist the deal, and celebrated its collapse in March 2024 as "a Biden win for flyers." Now the airline is gone, its workforce scattered, and the travelers Warren claimed to be protecting face fewer options and higher fares.
Transportation Secretary Sean Duffy held a Saturday morning press conference and laid the blame directly on the prior administration and its allies:
"There was a proposed merger between JetBlue and Spirit, and Joe Biden and Pete Buttigieg, along with the Biden DOJ, decided that they did not want that merger to take place."
Duffy did not stop there. He said the outcome vindicated those who warned against blocking the deal at the time.
"This merger should have been allowed, and this today would indicate this is not better for travelers, this is not better for pricing, this is not better for competition, actually, it's worse."
The timeline is damning for Warren and the Democrats who joined her campaign against the merger. JetBlue first announced its bid for Spirit in July 2022. By June 2023, Warren and eight House Democrats, including Rep. Alexandria Ocasio-Cortez, had sent a letter to then-Transportation Secretary Pete Buttigieg urging the DOT to keep blocking the deal.
Their letter asked Buttigieg's agency "not to be pressured by misleading comments generated through JetBlue's Astroturf campaign, and to continue its careful scrutiny of the JetBlue-Spirit deal." The Biden DOJ's Antitrust Division took the case to court.
In January 2024, U.S. District Judge William G. Young ruled the merger violated the Clayton Antitrust Act of 1914. JetBlue called off the acquisition by March 2024. The very next day, Warren posted on X, declaring the Biden administration's DOJ and DOT "were right to stand up for consumers and fight against runaway airline consolidation."
She added: "This is a Biden win for flyers!"
That post aged poorly. Spirit filed for bankruptcy later in 2024. A proposed half-billion-dollar government bailout fell through. And on Saturday morning, the airline shut its doors for good.
Republican Ohio Sen. Bernie Moreno wasted no time on Saturday. He posted Warren's celebratory March 2024 message alongside his own response:
"The 14,000 employees at Spirit who've lost their job loss, the travelers who will now pay higher fares, and the shareholders and debt holders who have been wiped out can thank Elizabeth Warren."
Moreno added: "Electing left politicians, who have ZERO business experience, has consequences." Before entering politics, Moreno owned more than a dozen car dealerships. Warren, by contrast, spent her career as an attorney and law professor before running for office.
Spirit had employed more than 17,000 workers and primarily served lower-income customers, the very people Warren routinely claims to champion. The airline's collapse leaves the "Big Four" carriers, American, Delta, Southwest, and United, controlling what Warren herself once acknowledged was 75 percent of the U.S. market. With Spirit gone, that share only grows.
The pattern is familiar in Democratic politics: progressive leaders intervene in markets on behalf of consumers, the intervention backfires, and the people who can least afford the consequences bear the heaviest cost. It is the same dynamic fueling broader revolts inside the Senate Democratic caucus, where members increasingly question whether their leadership's instincts match the needs of working-class voters.
Warren fired back on X Saturday, attempting to redirect blame. She wrote that "spiking fuel prices from Trump's war" were "the nail in the coffin for twice-bankrupted" Spirit. She also pointed out that the merger was ultimately blocked by a federal judge appointed by Ronald Reagan, not by her personally.
"FWIW, JetBlue merger failed because a judge, appointed by Ronald Reagan, said the deal was illegal. Republicans are desperate to shift blame from higher costs hitting families."
The argument has a surface logic. Warren did not issue the ruling. Judge Young did, citing a century-old antitrust statute. But Warren's defense sidesteps the lobbying campaign she led to get the government to challenge the merger in the first place. The judge ruled on a case the Biden DOJ brought, a case Warren publicly championed and pressured the administration to pursue.
As for fuel prices, GasBuddy analyst Patrick De Haan offered context Saturday morning. He noted that Spirit's restructuring plan assumed jet fuel costs of about $2.24 a gallon in 2026 and $2.14 in 2027. By the end of April, prices had climbed to roughly $4.51 a gallon, more than double the airline's projections. Warren attributed the spike to the closure of the Strait of Hormuz and the situation in Iran.
Rising fuel costs may well have accelerated Spirit's demise. But the airline was already in bankruptcy, already failing to find a buyer, and already losing its government lifeline. The merger that might have saved it never happened, because Warren and her allies made sure of that.
Economist and investor Peter Schiff replied directly to Warren's Saturday post, cutting to the core of the contradiction. As the New York Post reported, Schiff challenged her reasoning head-on:
"So why did you block the Jet Blue, Spirit Airlines merger? The combined company would have been better competition than Jet Blue alone. now that Spirit is gone thanks to your intervention."
Schiff's point is straightforward. Warren argued the merger would reduce competition. Instead, blocking it eliminated a competitor entirely. The market now has one fewer airline, not one more. Every traveler who relied on Spirit's rock-bottom fares will now pay more.
Duffy acknowledged that airline mergers deserve careful scrutiny. He said it is "important that we always look with a keen eye when airlines want to merge." But he drew a sharp distinction between prudent review and ideological obstruction.
"If the markets are saying there needs to be a merger because there's health issues with one of the airlines, or more than one airline, we have to take a look at it and make sure we make the right choices."
He concluded: "And in this situation, history has judged the denial of the merger between JetBlue and Spirit through the Biden administration with I think a view that it was a massive mistake."
Warren's record on this issue is now a case study in unintended consequences. She warned that the JetBlue-Spirit merger would lead to "fewer flights and higher fares." Blocking the merger produced exactly that outcome, along with thousands of lost jobs and a bankrupt airline that no longer exists.
The senator who built her brand on protecting consumers from corporate consolidation helped create the very consolidation she warned against. The Big Four carriers now face one fewer rival. Budget-conscious travelers, disproportionately lower-income Americans, have lost their cheapest option.
This is not an isolated episode of Democratic leadership producing results that contradict its stated goals. The party's internal fractures have only deepened as rank-and-file members watch their leaders' policy instincts collide with reality. Those tensions have surfaced everywhere from recruitment battles over Chuck Schumer's leadership to growing questions about whether the caucus can hold together heading into the next election cycle.
Warren's attempt to shift blame to fuel prices and a Reagan-appointed judge may satisfy her base. But the facts tell a cleaner story. She lobbied to kill the merger. The administration she pressured killed it. The airline died. And the workers and travelers she claimed to protect paid the price.
Duffy noted that Warren "cheered the blocking of the merger" at the time. Now, with Spirit's gates dark and its planes grounded, the cheering has stopped.
The broader question for Democrats is whether voters in 2026 will remember who celebrated when the deal collapsed, and who lost their jobs when the consequences arrived. With Senate Democrats already counting votes over their own leadership's future, episodes like this one do not help the party's case that it governs in the interest of working families.
Warren wanted to protect consumers from a merger. She got them something worse: no airline at all. That is what happens when politicians with zero skin in the game make decisions for the people who have to live with the results.
