British travellers have cause to celebrate after Jet2 reassured customers that their summer holidays will proceed as normal, confirming it has ample fuel and will not impose surcharges.The UK’s third-largest airline announced on Wednesday that it has received "positive updates" from its fuel suppliers, detailing increased production and additional imports from areas unaffected by the Middle East conflict.This positive news comes despite the head of the International Air Transport Association (IATA) warning travellers to brace for higher air fares as airlines can no longer absorb the escalating costs stemming from disruptions in the Strait of Hormuz.Willie Walsh, IATA's director general, informed the BBC that while there is no immediate concern regarding potential jet fuel shortages, the inevitable consequence of rising fuel prices will be an increase in air ticket costs.He said: "There may be some instances where airlines will discount to stimulate some traffic flow… but over time it’s inevitable that the high price of oil will be reflected in higher ticket prices."Airlines dramatically escalated flight cancellations for May, as the industry grapples with soaring jet fuel prices and concerns over potential shortages.Data from aviation analytics firm Cirium shows 296 departures from UK airports were cancelled in May, representing 0.75 per cent of the total scheduled flights. This marks a significant increase from just 120 cancellations reported six days prior.However, the outlook for the peak summer travel period appears more stable. Week-on-week schedule reductions for June remain limited at 48 fewer outbound flights, following the cancellation of 0.2 per cent of services. July has seen a reduction of 31 flights week-on-week, while August shows a minimal decrease of just four flights.German carrier Lufthansa and Turkish Airlines account for a substantial proportion of these grounded services, with both airlines opting to cancel flights as a cost-saving measure. In the UK, some Lufthansa operations have been affected, though this often means passengers are re-routed, for instance, those planning to fly from Glasgow to Frankfurt may now depart from Edinburgh.Lufthansa aircraft landing at Frankfurt, where thousands of flights have been cancelled. (AFP/Getty)Heathrow Airport has recorded just over 100 cancellations. However, these are not new disruptions but rather extensions of previously planned operations to airports in the Gulf region, where resumption dates have been further delayed.However, airports are set to ease regulations, allowing airlines to cancel flights without forfeiting their allocated "slots" – the scheduled times for take-off or landing – should fuel scarcity prevent them from operating.Below is a list of how airlines are responding, in alphabetical order:Aegean AirlinesThe Greek airline expects suspended Middle East flights and a spike in fuel prices to have a "notable impact" on its first-quarter results.AirAsia XThe Malaysian carrier said it would suspend services on routes between Melbourne and Denpasar and Adelaide and Denpasar from June 18 due to increased fuel prices.

A spokesperson said: “We are not seeing jet fuel supply interruptions, but fuel prices have risen sharply and, despite our hedging strategy, which gives some shorter-term mitigation, we are not immune to the impact.”However, The Independent’s Simon Calder has reassured customers “not to fret”.“BA will not come after you for more cash, and the airlines can charge only what the market will bear. And judging from some of the prices on offer, that isn’t a lot,” he said.IAG company also warned its profits will be hit as it expects to spend about €2bn (£1.72bn) more than planned on fuel this year. But Chief executive Luis Gallego said IAG does not believe there will be “any interruption for the summer” in terms of jet fuel supplies.Cathay PacificThe Hong Kong airline said it would cut some flight from mid-May until the end of June, cancelling about 2% of its scheduled passenger flights, while its budget airline HK Express was cutting around 6% of flights.The carrier previously said it would hike its fuel surcharge by 34% across routes from April 1 and review them every two weeks.The airline raised HK$2.08 billion ($265.58 million) from three-year fixed-rate notes at a yield of 3.78%, according to a term sheet seen by Reuters on Wednesday.Cebu AirThe Philippines-based airline said it had implemented fare adjustments and surcharges across parts of its network in response to ​fuel price pressures.China Eastern AirlinesThe airline said it would raise ⁠fuel surcharges for domestic flights from 5 April, with flights of 800km and below hit with a 60 yuan ($9) surcharge and a 120 yuan surcharge for flights over 800km.Delta Air LinesDelta said it would cut capacity by around 3.5 percentage points from its original plan and raise fees for checked ​bags in an attempt to offset soaring ⁠jet fuel costs, with an increase of $10 on first and second checked bags and a $50 increase on the third.The U.S. ‌airline pulled all planned capacity growth for the current quarter and forecast profit below Wall Street expectations.
