Tensions in the Strait of Hormuz have triggered sharp rises in jet fuel prices and warnings of potential shortages at European airports within weeks. For many UK travellers, shifting to car hire holidays in France, Spain or closer Mediterranean destinations offers greater reliability and cost control in 2026.
According to CNBC, the ongoing effective closure of the Strait of Hormuz — triggered by conflict involving Iran — has halted around 20 % of the world’s previous oil traffic, leading to jet fuel prices surging over 100 % month-on-month in some benchmarks.
Consequently, The Times reports that jet fuel benchmarks have risen by up to 130 % year-on-year, with a barrel reaching almost $200, while The Sun notes major UK carriers responding with fuel surcharges and route adjustments.
Airports Council International Europe has warned that if tanker traffic does not resume significantly within the next three weeks, a systemic jet fuel shortage could become reality across the EU, with particular pressure on Mediterranean leisure airports.

Impact on flights and fares
Major carriers have begun to respond. As reported by The Times, Virgin Atlantic has introduced fuel surcharges of up to £360 on certain flights from 14 April, while Ryanair has signalled possible capacity reductions if the situation persists into May or June.
The Sun adds that SAS has cancelled thousands of flights due to fuel concerns, and other operators including Lufthansa have prepared contingency plans. UK-based airlines currently benefit from more diverse supply chains and hedging, yet post-Easter and summer fares are expected to rise as costs are passed on to passengers.
Sunset Weekly analysis While these developments primarily affect air connectivity, they create a clear pivot point for British holidaymakers. Demand is likely to shift toward shorter-haul destinations reachable by a combination of Eurostar, ferry and car hire, reducing exposure to volatile aviation fuel costs. This aligns with our ongoing observation that ground-based travel often delivers more predictable budgeting during periods of global supply tension.

Practical advice for 2026 summer holidays
Book early where possible to secure current rates, particularly for popular Mediterranean routes. Flexible tickets provide protection should cancellations occur. For package holidays, operators must offer a full refund or suitable alternative under the Package Travel Regulations if a flight is cancelled.
Consider building your own itinerary using rail-and-sail options followed by car hire at the destination. This approach often delivers better value and greater flexibility when fuel availability at smaller airports comes under pressure.
Insider tip from the Sunset Weekly team Our local expertise in European driving routes shows that hiring a car in Marseille or Barcelona and exploring the surrounding regions frequently proves more relaxing and economical than relying on multiple short-haul flights during periods of supply uncertainty.

How this affects car hire and ground transport
Higher jet fuel costs may indirectly support demand for road-based holidays. Petrol prices at the pump in mainland Europe remain more stable in many regions compared with aviation fuel volatility. Renting a vehicle upon arrival allows travellers to adjust plans in real time without worrying about flight availability.

FAQs
Will my summer flight be cancelled due to the jet fuel shortage? At present, widespread cancellations remain limited for UK departures, though some carriers have trimmed schedules. UK airlines benefit from diverse sourcing and hedging through to mid-May in many cases. Monitor your booking closely and purchase flexible tickets or travel insurance that covers disruption.
How much more will flights cost in summer 2026? Fuel surcharges have already appeared, with Virgin Atlantic adding up to £360 on certain services. Expect higher base fares post-Easter as airlines recover costs. Booking sooner rather than later helps lock in current pricing where hedges still apply.
Is it safer to choose a car hire holiday instead? For many British travellers, combining ferry or Eurostar travel with car hire in France or Spain reduces reliance on aviation fuel. These options often prove more resilient during supply shocks and allow greater freedom once at your destination.
Can I still fly to Spain or Greece this summer? Yes, but expect possible price increases and thinner fuel margins at island airports. Mediterranean leisure destinations may face greater pressure if the Hormuz situation continues. Shorter sectors from the UK currently show fewer immediate issues.
What should I do if my flight is cancelled? For package holidays, your operator must provide a refund or rerouting. Independent flight bookings entitle you to a refund or alternative flight, potentially on another carrier. Always check the precise terms of your ticket and insurance policy.
Are there any unaffected holiday options? Closer European destinations reachable by train and car, or domestic UK breaks, currently face lower risk. Some resort areas report minimal direct impact, though overall aviation costs still influence pricing across the board.
