Global airlines are confronting an additional $100 billion in jet fuel costs this year after the closure of the Strait of Hormuz in March sent oil prices sharply higher. The International Air Transport Association has slashed its industry profit forecast in half to $23 billion in response to the fuel shock, warning that ticket price increases are now unavoidable.

The surge stems from geopolitical tensions in the Middle East, where Iran's military actions have disrupted oil supplies. Jet fuel prices are expected to remain 70 percent higher throughout 2026 compared to previous forecasts. Airlines typically hedge fuel costs months in advance, but the sudden price spike has caught many carriers with insufficient protection against increases.

"High oil prices will inevitably mean higher ticket prices," said Willie Walsh, director general of the International Air Transport Association. "There's just no way to avoid that." Walsh acknowledged that the situation poses existential risks to some carriers, though he stressed that the industry remains profitable and is still forecasting growth. He noted that concerns about fuel shortages have eased despite the elevated costs.

Airlines are responding by adjusting financial projections and implementing cost-cutting measures. Long-haul and business class passengers are likely to face the steepest fare increases. Sean Doyle, chief executive of British Airways, explained that carriers with significant long-haul and premium offerings would pass through more of the fuel costs to customers than competitors focused on price-sensitive short-haul routes.

Research from the airline industry body indicates that around half of passengers are willing to pay substantially more for fares if prices track oil costs. This willingness to spend more offers hope for a strong summer travel season, particularly as British and European travelers opt for continental flights rather than venturing farther afield amid ongoing uncertainty around Middle Eastern hubs.

The fuel crisis compounds existing pressures on aviation profitability. Airlines have called out aircraft engine manufacturers for pricing practices that add to financial burdens, creating dual cost pressures that could reshape competitive dynamics and potentially reduce service on less profitable routes.

Industry leaders at a recent summit in Rio de Janeiro highlighted another emerging challenge facing European travel. The European Union's new entry-exit system for border controls, set to take full effect by September 7, could create bottlenecks at airports. The system will require fingerprinting and photographing of most non-EU visitors, potentially slowing passenger processing from 20-25 seconds to 90 seconds per person. Officials warn this could create significant delays, particularly affecting Mediterranean destinations that rely heavily on British tourists. Some airports may struggle to implement the system reliably, adding uncertainty for summer travel planning.
