The Hormuz Crisis Is Splitting the Airline Industry in Two

The Strait of Hormuz has shut and reopened, shut and reopened, and shut again since February. It closed in late February after U.S.-Israeli strikes on Iran, reopened briefly in mid-April, was re-closed on April 20, reopened again via a May 29 ceasefire that sent oil down 10 percent in a week, opened once more on June 15 with crude falling toward $80 — and is now effectively shut, with transit volumes down roughly 95 percent ^[1][2][3][4]. Each reopening was met as the end of the crisis. Each time the strait shut again.

2026-02 Strait closes after U.S.-Israeli strikes on Iran

2026-04 Briefly reopens, then re-closed April 20 ^[1]

2026-05 Reopened via ceasefire; oil drops 10% in a week ^[2]

2026-06 Reopened again; crude falls toward $80 ^[3]

2026-08 Effectively shut; transit down ~95% ^[4]

The reopenings are false dawns. ExxonMobil's Neil Chapman warned that global inventories are at what he called really, really low levels — unheard of inventory levels — and that once depleted, prices will shoot up ^[2]. Aramco's CEO described the closure as the largest oil supply shock in history, removing roughly 2.6 billion barrels since late February, and warned it would take up to 18 months to replenish inventories even after the strait reopens ^[5]. A reopening does not refill the tanks. The supply destruction persists for months after the ships start moving again. The result is a whipsaw that would strain any hedging strategy. A carrier that locked in fuel prices when the strait briefly reopened in April would have been exposed again when it re-closed weeks later. A carrier that bought forward after the May ceasefire would have been caught by the June reopening's false signal. The Association of Asia Pacific Airlines warned in May that fuel hedging contracts across the region expire in the second quarter of 2026 — meaning the protective buffer that shielded carriers from the initial price spike is burning off precisely as the cycle persists ^[6]. The danger may be less the price level than the volatility itself: a carrier can budget for expensive fuel, but it cannot budget for fuel that doubles against its planning assumptions between quarterly forecasts. That is what killed Spirit Airlines. The carrier's restructuring plan assumed jet fuel at $2.24 per gallon. The Hormuz crisis pushed it to $4.24 — nearly double ^[7]. The math of the restructuring became impossible. Spirit ceased all operations on May 2 after a $500 million federal bailout collapsed when creditors rejected the terms; 17,000 jobs were lost ^[8]. The Association of Value Airlines requested a $2.5 billion liquidity pool to protect other budget carriers from the fuel shock. Transportation Secretary Duffy rejected it ^[8]. Now set that against Delta Air Lines. Delta absorbed a $1.65 billion year-over-year increase in fuel costs — and its operating income fell by only $238 million ^[9]. Its shares rose nearly 50 percent over twelve months. The difference is not luck or better management. It is structural. Delta and United built their post-pandemic strategies around premium travel — first-class cabins, corporate contracts, loyalty programs that generate revenue before a single seat is sold. Budget carriers like Spirit built theirs around volume and cost discipline, which works when fuel is predictable and fails when it is not. Even before the Hormuz crisis, the U.S. airline industry was bifurcated: Delta and United dominated profits through premium strategies while budget carriers were already in bankruptcy ^[10]. The fuel shock did not create the divide. It widened it into a chasm, then made the chasm permanent. The same dynamic is playing out globally. Ryanair's Michael O'Leary warned in April that 10 to 25 percent of the carrier's fuel supplies could be at risk during May and June, and threatened 5 to 10 percent flight cancellations through July ^[11]. Cathay Pacific raised fuel surcharges 34 percent and warned it might not be able to sustain its network ^[12]. SkyBus, a British regional carrier, cancelled all London Gatwick–Newquay flights, calling the fuel rise and a drop in passenger bookings an insurmountable barrier ^[11]. Europe has less than 30 days of jet fuel demand cover remaining — the tightest supply coverage of any major global aviation market ^[13]. The consolidation is already visible in the numbers. After Spirit's collapse, four major U.S. carriers now control approximately 75 percent of the domestic market ^[14]. IATA halved its 2026 global airline profit forecast from $45 billion to $23 billion, with jet fuel adding $100 billion to the industry's collective fuel bill ^[15]. American Airlines' Q2 net income collapsed from $599 million to $71 million year-on-year despite a 16.3 percent revenue increase — record demand cannot outrun the fuel cost shock ^[16]. United Airlines CEO Scott Kirby pitched merger discussions to both Delta and American Airlines — exploring a $100 billion mega-carrier that would control roughly half the U.S. domestic market — before pivoting to buying individual airport slots and gates when full mergers hit antitrust barriers ^[17]. Airlines for America's head Chris Sununu testified before Congress that we have more competition per route than ever before ^[14]. The claim is technically true in the sense that any given route may have multiple carriers on it. It is also a dry evasion of the fact that fortress hubs — where a single airline controls over 70 percent of flights — are the industry's actual structure, and that structure just got more concentrated. Major U.S. carriers raised domestic economy fares 21 percent year-on-year to an average of $570, and United's Kirby has said higher prices may persist even if fuel normalizes ^[18]. That is the permanence the crisis has bought. The fuel shock provided the cover to raise fares to a level the industry wanted anyway; the consolidation ensures there are fewer competitors to undercut them. The crisis is the catalyst. The new structure does not need the crisis to survive it.
