I’ve Seen This Movie Before: The Gulf War Killed Trump Shuttle. The Iran War Just Killed Spirit.

On May 2, 2026, Spirit Airlines ceased operations — abruptly, with 17,000 people out of work and roughly 1.8 million booked passengers scrambling for alternatives. The bright-yellow planes went dark. Customer service went silent. America’s first major airline liquidation in 25 years was complete in a matter of hours.

The commentators called it unprecedented. The analysts called it a perfect storm. I called it familiar.

I’ve been in this room before.

1989: The Room Where It Happens

Eastern Airlines filed Chapter 11 in March 1989. What followed was one of the most complex, contentious, and ultimately tragic corporate restructurings in American aviation history. Frank Lorenzo’s Texas Air Corporation had driven the carrier to its knees — labor wars, cash hemorrhage, a fleet financing structure held together with baling wire and optimism. I worked that bankruptcy alongside Martin Shugrue, who served as Eastern’s court-appointed trustee, navigating a wreckage of aircraft leases, creditor claims, union contracts, and political pressure that would have broken less-determined men.

The crown jewel that came out of that process was the Eastern Shuttle — the Boston-New York-Washington corridor operation that had been running since 1961. In 1989, Donald Trump acquired it for approximately $365 million, rebranding it as the Trump Shuttle with the full gilded-logo treatment. It was a high-profile deal, and for a moment it looked like a smart one.

Then the Gulf War started.

The Fuel Spike That Changed Everything

Iraq’s invasion of Kuwait in August 1990 sent crude oil prices surging almost overnight. Jet fuel — the second-largest cost center for any airline after labor — spiked violently. For a legacy carrier with a diversified route network and pricing power, that’s painful. For a shuttle operation running on thin margins between three cities with a highly leveraged debt load, it was a death sentence written in fuel surcharges.

Trump Shuttle couldn’t raise fares enough to cover the spike without losing the business travelers it depended on. It couldn’t cut costs fast enough. It defaulted on its debt in 1990. By 1992, the lenders — led by Citibank — had taken control, and the Trump Shuttle name was finished. The operation eventually became US Airways Shuttle.

The formula was simple and brutal: leverage plus thin margins plus an exogenous fuel shock equals liquidation. There was no complexity to it. There was just math.

2026: Different Airline, Same Equation

Spirit Airlines had been bleeding for years before the Iran war started. Two Chapter 11 filings in less than 18 months. A blocked merger with JetBlue. Engine groundings. A business model built on ultra-low base fares that the big legacy carriers had undercut by launching their own basic economy products — with bigger networks, free Wi-Fi, and airport lounges on top.

Then the Iran war started, and oil markets did what oil markets always do when 20 percent of global supply goes sideways: they spiked. Hard.

Spirit, already in its second bankruptcy, already negotiating a last-ditch $500 million federal rescue with the Trump administration, already watching its market share crater from 5 percent to under 2 percent, simply ran out of runway. The creditors balked at the rescue deal terms. The fuel math stopped working. And on May 2, an airline that had operated for 34 years told 17,000 employees they were done — with about an hour’s notice.

It is almost precisely the Trump Shuttle pattern, scaled up and played out over a longer timeline. The underlying mechanism is identical: a structurally weakened carrier, over-leveraged and under-capitalized, absorbs an exogenous energy shock it cannot pass through to price-sensitive customers, and the capital structure collapses.

What the Analysts Keep Getting Wrong

Every post-mortem I’ve read on Spirit focuses on the proximate causes — the JetBlue merger block, the engine issues, the fuel costs, the bankruptcy filings. These are all real. But they’re symptoms, not the disease.

The disease is structural. Ultra-low-cost carriers live and die on cost advantage. The moment that advantage erodes — whether through fuel shocks, labor cost normalization, or legacy carriers learning to play the same fare game — the business model collapses because there is no margin buffer to absorb anything. Spirit was not a resilient business that got hit by bad luck. It was a structurally fragile business that got hit by predictable risks.

I saw the same thing with Trump Shuttle. The deal looked brilliant in 1989. The assumptions built into it did not survive contact with August 1990. The difference between a workout and a liquidation is almost always whether the capital structure can be right-sized before the next exogenous shock arrives. In Eastern’s case, the assets were preserved and redistributed — including those Latin American routes that went to American. In Trump Shuttle’s case, the lenders eventually recovered through asset control. In Spirit’s case, there was nothing left to restructure. The assets will be absorbed by the surviving carriers, the routes will be redistributed, and in six months most passengers won’t notice Spirit is gone except when they see a fare increase on routes Spirit used to fly.

The Larger Lesson

Spirit’s collapse is being framed as a tragedy of bad timing — a solid business killed by a war it couldn’t have predicted. That framing is wrong, and it matters that we get it right, because the same structural vulnerabilities exist in other carriers today.

An airline that cannot survive a 20 percent fuel cost increase was not a viable airline. It was a viable airline in stable conditions, which is a different thing entirely. The Gulf War was not unforeseeable — the Middle East has been a source of oil supply disruption risk for half a century. The Iran conflict is not unforeseeable either. These are known risk categories. Building a capital structure that cannot absorb them is a choice, usually driven by the pressure to maximize near-term growth at the expense of balance sheet resilience.

Martin Shugrue used to say that airline bankruptcies were never really about the airlines. They were about what the people building the capital structures believed would never happen. He was right in 1989. He would have been right about Spirit in 2026.

The names change. The math doesn’t.
