The UK government is preparing for possible summer travel disruption by allowing airlines to cancel or combine flights in advance without losing valuable airport slots. The temporary move comes as global jet fuel markets remain under pressure following conflict-linked disruption around the Strait of Hormuz, one of the world’s most critical oil shipping routes.Under normal aviation rules, airlines operating at busy airports such as Heathrow and Gatwick must use at least 80% of their take-off and landing slots or risk losing them to competitors. The system is commonly known as the “use it or lose it” rule.Now, the government wants to temporarily relax those rules so airlines can reduce schedules early if fuel supplies tighten later in the summer. Officials say the goal is to avoid sudden cancellations at airports and stop airlines from operating near-empty “ghost flights” simply to protect their airport slots.Transport Secretary Heidi Alexander said the measures are designed to give families “greater confidence” while helping airlines plan realistic schedules in advance. According to the Department for Transport, there are currently no immediate jet fuel shortages in the UK, but contingency plans are being prepared before the busy holiday season intensifies.
Strait of Hormuz crisis across Europe
The growing concern comes after severe disruption to fuel shipping routes linked to escalating tensions in the Middle East. The Strait of Hormuz, through which roughly one-fifth of the world’s oil and gas passes, has become a major pressure point for global energy markets.Industry data cited in recent reports showed Gulf jet fuel exports fell sharply during the crisis period, adding to fears that airlines across Europe may struggle with higher costs and tighter fuel availability during peak travel months.The UK government has already asked domestic refineries to maximise jet fuel production as part of wider contingency planning. Energy Minister Michael Shanks confirmed officials are working closely with airlines, airports and fuel suppliers to monitor stock levels daily.Although British airlines say they are not yet experiencing direct shortages, several carriers across Europe have already started adjusting operations. Lufthansa reportedly cancelled thousands of flights to conserve fuel and manage costs.The uncertainty has also increased pressure on aviation finances. Airlines are facing sharply rising fuel prices, unpredictable passenger demand and operational planning challenges simultaneously.
What the new UK Airline rules mean?
The government says the new approach intends to reduce stressful last-minute disruptions rather than create more cancellations. Instead of grounding flights hours before departure, airlines would be encouraged to make decisions much earlier and move passengers onto alternative services in advance.Officials say the flexibility would allow airlines to:
- combine multiple flights to the same destination,
- avoid unrealistic schedules,
- reduce fuel waste from lightly booked aircraft,
- and protect passengers from airport-day chaos.
Importantly, passenger rights remain unchanged. Under UK law, travellers whose flights are cancelled are still entitled to either:
- a full refund, or
- an alternative flight arrangement.
However, airlines are also lobbying the government to classify fuel shortages as an “extraordinary circumstance,” which could allow carriers to avoid paying additional compensation for short-notice cancellations.The government has meanwhile advised travellers to continue checking airline updates before departure and ensure they have suitable travel insurance in place.
Airlines face pressure
The fuel disruption concerns are arriving at a difficult moment for the aviation industry, which is already struggling with the high cost of sustainable aviation fuel (SAF). Britain introduced SAF blending mandates in 2025 requiring fuel suppliers to gradually increase the amount of cleaner aviation fuel used on flights.But airlines and fuel suppliers say production remains too limited and expensive. Industry groups have warned that sustainable fuel supplies are nowhere near the levels needed to meet long-term climate targets.The International Air Transport Association (IATA) has repeatedly warned that SAF currently represents less than 1% of global jet fuel use, while costs remain several times higher than conventional fuel.For now, the UK government insists there is “no current need” for passengers to cancel or change holiday plans. But behind the scenes, officials are clearly preparing for a difficult summer if global fuel supply tensions worsen further.
