EU holds five months of reserve supply, but rerouting costs add roughly $100 to long-haul fares
Briefing
The Gulf War triggered a sharp jet fuel price spike that forced airlines including Continental and Midway into bankruptcy. The transmission channel was identical: Middle East supply disruption, fuel surcharges layered onto a demand-sensitive fare base, and thinner carriers unable to sustain hedging programs through the shock.
Jet fuel hit record highs during the oil price spike, prompting US and European carriers to ground fleets, impose fuel surcharges, and accelerate capacity cuts. Several low-cost carriers exited the market entirely, and the episode established that airlines with less than six months of hedged fuel exposure face existential risk in sustained supply shocks.
Russia's invasion of Ukraine triggered European airspace rerouting, adding hours and fuel burn to long-haul routes and demonstrating that geopolitical airspace closures compound fuel cost increases multiplicatively rather than additively, since rerouting raises per-flight consumption precisely when fuel prices are highest.

The IEA chief's warning that Europe had roughly six weeks of jet fuel remaining if Gulf supplies stayed blocked is now being validated by airline warnings of imminent shortage severe enough to disrupt summer schedules, confirming the depletion timeline is tracking the worst-case scenario.

The US Navy's seizure of an Iranian vessel near Hormuz, which reimposed shipping restrictions after a brief reopening, directly extended the supply disruption now driving the jet fuel shortage and the 24% airfare increase.

The Trump administration blocking a United-American merger removes a potential capacity consolidation mechanism that could have helped US carriers absorb fuel cost shocks through pricing power, leaving the industry more exposed to margin compression.
