Airlines are starting to cancel flights as they face jet fuel shortages and rising prices brought on by the Iran war

Jet fuel spiked to $195 at the end of March (up nearly $100 since end-February) as the US/Israel–Iran war disrupts Middle East supply and traps oil in storage; crude has moved above $100/barrel. IEA warns April oil losses will be double March's and shortages will spread to Europe; United warns sustained prices would add ~$11 billion in annual jet-fuel expense. Carriers are already cutting capacity—Air New Zealand trimming ~5% (~1,100) flights in May, SAS cutting ~1,000 flights, Vietnam Airlines suspending routes and warning of 10–20% monthly cuts if jet fuel reaches $160–$200/barrel—creating near-term margin pressure and capacity shocks across airlines and travel-related sectors.

Analysis

Airline P&L sensitivity to refined-product dislocations is underappreciated by consensus: carriers with hub-and-spoke networks suffer two hits — direct fuel burn and an amplified revenue loss from network thinning as feeder frequency drops and premium connecting traffic is rerouted or re-accommodated. That dynamic favors cargo and point-to-point low-cost carriers that can flex capacity quickly, while large legacy carriers with fixed widebody schedules and long-term contract obligations face outsized margin compression over the next 1–3 quarters.

A scarcity premium is forming in the refined-product complex that won't resolve on crude flows alone; jet fuel requires specific tankage and yield slates at refineries are sticky for weeks. This creates a window where refiners with flexible stream switching and storage owners/tankers capture outsized spreads, and where options on ULSD/HO or physical jet cracks become high-expected-value trades relative to crude outright exposure.

Timing and reversal catalysts are concrete and near-term: market structure (refinery maintenance season, storage availability) points to a 4–12 week elevated-risk period; diplomatic or SPR action can compress cracks within 2–6 weeks, while refinery throughput adjustments take multiple turnaround cycles (months). Monitor quarterly hedging roll dates, refiner utilization prints, and front-month jet cracks as early-warning reversal signals.

Key Decisions for Investors

• Short UAL via a 3–6 month put spread (buy ~25-delta put, sell ~10-delta put) to cap premium outlay. Rationale: limits downside to the net premium while paying off materially if fuel-driven margin misses force a re-rate; target 2.5–4x skewed payoff if guidance is cut at next quarter. Close on signs of hedging relief or SPR announcements.
• Long ULSD/HO call spread (1–3 month) to play widening jet/diesel cracks versus Brent. Use a calendar ladder: stagger expiries to monetize multi-week scarcity. Risk: premium loss if cracks compress from diplomatic resolution; reward: captures refining/TAS tightness with asymmetric upside vs crude exposure.
• Pair trade: short UAL / long UPS (3–6 month). Short the airline equity to capture near-term margin shock and hedge by buying UPS outright (or buying a 3–6 month call) to capture improved cargo yields from passenger capacity shrink. Risk/reward: limited downside on the hedge side, upside if cargo pricing sustains.
• Buy calls on regional independent refiners with flexible yields (e.g., PBF, VLO) 3–6 month expiries or use small outright exposure. Rationale: these names capture jet/ULSD cracks more directly than majors; close position on refinery utilization increases or if cracks revert rapidly.
