UK Unveils Aviation Fuel Contingency Plan: Airlines Can Cancel Flights Weeks in Advance

The UK government has unveiled a new aviation contingency plan that will allow airlines to cancel flights weeks in advance without losing valuable airport takeoff and landing slots, in response to potential jet fuel shortages caused by the disruption to Middle East supplies amid the Iran war.

Key Provisions

Under the new plan, carriers will be able to adjust their schedules at least two weeks ahead of potential fuel problems — for example, by cutting one or two flights a day on routes where they operate multiple services to the same destination.

Normally, airlines are reluctant to do this because it would risk their right to retain allocated slots at busy airports like London’s Heathrow and Gatwick. Such slots can be worth tens of millions of pounds and change hands only rarely. Under existing rules, slots allocated over a summer or winter season roll over to the following year — but only if they are used at least 80% of the time, otherwise they can be seized by rival airlines.

The new measures will allow airlines to temporarily hand back unused slots while retaining the right to use them the following year.

The Iran War’s Ripple Effect

The UK imports approximately 65% of the jet fuel it uses, a significant portion of which normally comes from the Middle East. However, the closure of the Strait of Hormuz means those supplies cannot get through.

While airlines say they are not currently experiencing fuel supply problems, experts have warned that disruption to deliveries caused by the Iran war could bring shortages within weeks.

Government Position

Transport Secretary Heidi Alexander said: “We’re preparing to give families long-term certainty and avoid unnecessary disruption at the departure gate this summer. This legislation will give airlines the tools to adjust flights in good time if they need to, which helps protect passengers and businesses.”

The government believes this approach will reduce the risk of last-minute cancellations, giving passengers and businesses a longer timeframe to make alternative arrangements.

Background and Implications

In late April, the government said that new guidance from Airport Coordination Limited (ACL) made clear that airlines would not lose their slots if a lack of fuel prevented them from flying. The new plan goes further by letting carriers anticipate problems rather than react to them.

These contingency measures reflect the far-reaching impact of the Iran war on the global aviation industry. The Strait of Hormuz, one of the world’s most critical oil shipping chokepoints, has seen its通行 disrupted — pushing up global energy prices and now beginning to affect fuel-dependent sectors including aviation and logistics.

For the UK aviation sector, this represents the most significant operational challenge since the COVID-19 pandemic. If fuel shortages persist, airlines may need to significantly reduce capacity, and passengers could face widespread delays and cancellations.
