Fuel shock redraws the map of flying

Air passengers face a tougher booking season as airlines trim connections, suspend weaker routes and ground aircraft to absorb a jet-fuel shock that has spread from energy markets into ticket prices and network planning. Industry officials are warning that the disruption could deepen through the northern summer, especially on thinner international and regional links where carriers have little room to absorb higher costs.

Jet fuel prices have surged far faster than crude, leaving airlines with a cost problem that goes well beyond the usual swings in oil. IATA’s fuel monitor showed the global average jet fuel price at $197.83 a barrel last week, while Reuters reported that prices had climbed from roughly $85-$90 a barrel to as much as $150-$200 in a matter of weeks. Fuel now represents about 27% of airline operating expenses, making it one of the industry’s biggest cost pressures after labour.

The immediate trigger has been the disruption to energy flows linked to the Iran war and the closure of the Strait of Hormuz, a chokepoint that has hit supply chains for aviation fuel more severely than many travellers might realise. Reuters reported that Europe is especially exposed because it relies on imports for about 75% of its jet fuel supply from the Middle East, while the Gulf remains a major supplier to the wider market. IATA director general Willie Walsh has said flights in Europe could start being cancelled from the end of May if shortages worsen, adding to fears of a strained summer season.

That pressure is already showing up in airline schedules. Air Canada said it would reduce daily flights to New York from 38 to 34 from June 1, temporarily cutting four JFK services as higher fuel prices make marginal routes less attractive. United Airlines has said it is cutting unprofitable flights over the next two quarters, while Lufthansa said it would ground as many as 27 aircraft and retire four older jets, one of the clearest signals yet that big carriers are prepared to shrink capacity rather than chase traffic at uneconomic fuel costs.

Across Asia, the changes are even more visible on domestic and secondary routes. Batik Air Malaysia has cut domestic capacity by 36%, describing the response as necessary in a crisis-mode environment. Vietnam Airlines plans to cancel 23 domestic flights a week, while VietJet has adjusted frequencies on selected routes. Cathay Pacific has said it will cancel about 2% of scheduled passenger flights from mid-May to late June, and HK Express about 6%, showing how network pruning is spreading from full-service operators to budget brands as well.

Passengers are also being asked to shoulder more of the burden. Airlines have introduced or raised fuel surcharges, pushed through fare increases and looked for ancillary revenue to soften the blow. Thai Airways has said fares will rise by 10% to 15%. SunExpress will impose a temporary €10 surcharge on routes between Turkey and Europe. United is raising checked-bag fees, and other carriers from Hong Kong to Canada have taken similar pricing steps. For travellers, that means the pain is no longer confined to cancelled flights; it is also appearing in the total cost of reaching the same destination.

Another shift is less visible to passengers but crucial for airline operations: carriers are carrying extra fuel or making refuelling adjustments to protect themselves against supply gaps. Reuters reported that some foreign airlines are resorting to “tankering”, loading more fuel than usual where supplies are more secure. That practice raises weight and fuel burn, making it an expensive insurance policy. Analysts cited by Reuters say some countries may already be limiting fuel access for foreign airlines, a sign that scarcity risks are moving from pricing into operational logistics.

The broader consequence is that global connectivity is starting to fray at the edges first. Thick trunk routes between major hubs may survive because airlines can still fill seats and charge more, but smaller cities, discretionary frequencies and price-sensitive leisure links are more vulnerable. Reuters reported that demand destruction in Asia has so far been modest compared with the scale of supply loss, suggesting deeper cuts may still be ahead if fuel remains scarce. That matters because airline networks are built like webs: once marginal connections disappear, onward itineraries become longer, more expensive and less reliable.
