Jet Fuel Shortages Loom, Forcing Airlines to Slash Flights

Airlines are confronting a new and more fundamental threat than just high prices: a potential shortage of the jet fuel needed to keep their fleets flying. The conflict with Iran has effectively closed the Strait of Hormuz, a vital shipping channel, severely restricting global supplies. In the U.S., the average price per gallon has nearly doubled since late February, with even steeper hikes abroad.

This supply crunch is pushing carriers to draft contingency plans that include grounding aircraft. Lufthansa's CEO confirmed internal teams are preparing for scenarios involving fuel scarcity. While the U.S. produces substantial jet fuel, the problem is local. Planes refuel at their destinations, meaning American airlines on international routes, particularly to Asia, are exposed.

United Airlines CEO Scott Kirby stated his airline will reduce its extensive Asian service. He warned the West Coast is especially vulnerable due to limited pipeline connections and refining capacity. Kirby told employees the airline is bracing for oil above $100 a barrel for years and is cutting some near-term flights to avoid 'burning cash.'

Analysts expect more schedule reductions. UBS noted U.S. capacity growth projections for this quarter are already being revised downward. 'We expect more capacity cuts in the coming weeks,' the firm reported.

The timing is severe, with the peak summer travel season approaching. Fuel is typically an airline's second-largest cost. Carriers like Delta, United, and JetBlue are raising fares and baggage fees to offset expenses, but there's a limit. 'Fuel at $4/4.50 a gallon for longer isn't something airlines can pass through,' said Raymond James analyst Savanthi Syth. 'If fuel stays high, you'll just see capacity being cut.'

The industry's resilience now hinges on sustained travel demand. Should high fuel prices begin to strain consumer wallets, leading to a pullback in spending, airlines will face a much deeper crisis. As one Fitch Ratings director noted, sustained prices at current levels could quickly pressure airline credit ratings.
