Department for Transport guidance first published on 24 April 2026 and updated on 8 May 2026 states that there is no current need for passengers to alter travel plans. The department says UK airlines are not reporting a jet fuel shortage, noting that carriers generally buy fuel ahead and that airports maintain bunkered stocks as part of standard resilience planning. (gov.uk) The immediate policy position is monitored continuity rather than emergency intervention. Ministers have presented the issue as a resilience and contingency matter, not as a present supply failure affecting UK departures. (gov.uk)
That position sits against the closure of the Strait of Hormuz and the wider instability linked to the Middle East conflict. According to the Department for Transport, ministers and officials have been monitoring jet fuel stocks daily and working with airlines, airports and suppliers while also pursuing a wider response intended to restore shipping flows. (gov.uk) The department has also said that domestic jet fuel production has increased and that the UK imports fuel from a range of countries that are not dependent on the Strait, including the United States. The practical point is that the government’s reassurance depends not only on stockholding but also on supply diversification. (gov.uk)
The latest cancellation data does not indicate system-wide disruption. In its 8 May update, the Department for Transport said Cirium data showed cancellations at 0.53% of planned UK flights for May 2026, while separate DfT analysis of OAG schedules recorded about 1,200 cancelled departures from the UK between 3 May and 14 June 2026, less than 1% of planned flights over that period and within the normal range. (gov.uk) The same update says that summer schedule reductions have mainly affected destinations closer to the Middle East. That points to a concentrated risk pattern on particular markets rather than a broad contraction across the UK aviation network. (gov.uk)
Official advice therefore remains cautious but unchanged. Passengers are advised to continue checking with their airline before departure, to follow Foreign, Commonwealth and Development Office travel advice, and to ensure that suitable travel insurance is in place. (gov.uk) That advice matches the government’s wider approach of active monitoring and early communication. The Department for Transport has said it is meeting industry regularly to understand pressures and to ensure passengers receive clear information if conditions change. (gov.uk)
Where cancellations do occur, the legal position is clearer than much of the public commentary suggests. The Civil Aviation Authority states that passengers covered by UK law must be offered a choice between a refund and alternative transport, and that this protection applies to flights departing the UK on any airline, flights arriving in the UK on an EU or UK airline, and flights arriving in the EU on a UK airline. (caa.co.uk) The Civil Aviation Authority also states that airlines must provide care and assistance while passengers wait, including reasonable food and drink, communication, accommodation where necessary, and transport to and from that accommodation. In the government’s wider summer 2026 guidance, significant delay thresholds for care are set at 2 hours for short-haul, 3 hours for medium-haul and 4 hours for long-haul services. (caa.co.uk)
Compensation is a narrower question than refund or re-routing rights. The Civil Aviation Authority says fixed-sum compensation may be available where a cancellation is notified with less than 14 days’ notice, but not where the disruption results from extraordinary circumstances that could not have been avoided even if reasonable measures had been taken. (caa.co.uk) For current conditions, that distinction matters. A passenger may still be entitled to re-routing, refund and care even where a separate compensation claim does not succeed because the airline argues that the cause fell outside its control. (caa.co.uk)
Alongside passenger guidance, ministers are adjusting the regulatory position for airlines. At slot-coordinated UK airports, carriers normally need to use at least 80% of an allocated slot series to retain equivalent rights in the next season, a rule commonly described as ‘use it or lose it’. Airport Coordination Limited’s force-majeure guidance sets out that 80% utilisation test, and the Department for Transport says ACL has updated its approach so airlines can apply for protection where fuel shortages prevent flying. (acl-uk.org) The policy intent is to reduce pressure on carriers to operate marginal services purely to defend future slot rights. That is relevant at airports where slot access is commercially significant and where schedule realism can matter as much as raw capacity. (gov.uk)
The Department for Transport’s separate 2 May 2026 announcement goes further by consulting on temporary measures for the summer 2026 and winter 2026 seasons. Those measures would allow airlines to hand back a limited share of slots or consolidate same-day services on routes with multiple flights to the same destination, with the stated aim of locking in realistic schedules earlier and cutting late cancellations. (gov.uk) Taken together, the package has two purposes. The first is to reassure passengers that there is no current UK jet fuel shortage. The second is to give airlines regulatory room to trim schedules earlier, rather than cancel late or operate lightly loaded services simply to protect future slot rights. (gov.uk)
