The international aviation industry is currently implementing operational modifications in response to escalating jet fuel costs and supply uncertainties stemming from geopolitical conflict in the Middle East.

國際航空業目前正針對噴擊燃料成本攀升以及中東地緣政治衝突導致的供應不確定性，採取營運調整措施。

The current instability is primarily attributed to the blockade of the Strait of Hormuz, a critical conduit for global petroleum distribution. This disruption has precipitated a significant increase in kerosene prices, which approximately doubled between February and April 2026. Consequently, aviation analytics firm Cirium reported the cancellation of approximately 13,000 flights in May, representing a 1.5% reduction in global capacity and the removal of two million available seats. Stakeholder positioning varies by institutional scale; legacy carriers, such as Lufthansa—which has terminated 20,000 flights through October—and Turkish Airlines, have implemented substantial reductions to mitigate financial losses. Conversely, low-cost carriers are characterized by the Royal Aeronautical Society as being more susceptible to demand sensitivity due to tighter profit margins and the utilization of less fuel-efficient fleets.

目前的動盪主要歸因於霍爾مز海峽的封鎖，該海峽是全球石油分銷的關鍵通道。這次擾亂導致煤油價格大幅上漲，在 2026 年 2 月至 4 月間幾乎翻倍。因此，航空分析公司 Cirium 報告 5 月份約有 13,000 個航班被取消，代表全球運能減少 1.5%，並減少了 200 萬個可用座位。持份者的立場隨機構規模而異；傳統航空公司，如漢莎航空（截至 10 月已取消 20,000 個航班）和土耳其航空，已實施大幅削減以減輕財務損失。相反，皇家航空學會指出，廉價航空由於利潤空間較窄且使用的機隊燃料效率較低，對需求的敏感度更高。

In the United Kingdom, the Department for Transport has asserted that there is no immediate fuel shortage, citing the efficacy of advance purchasing and airport reserves. Nevertheless, the administration has introduced contingency measures to facilitate operational flexibility. These include the suspension of 'use it or lose it' slot regulations, allowing carriers to cancel or merge flights without forfeiting landing rights. This regulatory rapprochement is intended to prevent last-minute disruptions by consolidating passengers onto fewer aircraft. Simultaneously, various carriers have sought to offset escalating overheads through the implementation of fuel surcharges and increased baggage fees, while some, such as Ryanair and Jet2, have maintained a policy of price stability for consumers.

在英國，運輸部聲稱目前沒有立即的燃料短缺，理由是提前採購和機場儲備的成效顯著。儘管如此，政府仍推出了應變措施以提高營運靈活性。其中包括暫停「不用即喪失」的時段規定，允許航空公司在不放棄起降權的情況下取消或合併航班。此監管寬限旨在透過將乘客集中到較少的飛機上，以防止最後時刻出現混亂。同時，多家航空公司試圖透過實施燃料附加費和調高行李費來抵消上升的開支，而部分公司如 Ryanair 和 Jet2 則維持對消費者的價格穩定政策。

On a global scale, the impact is heterogeneous. The European Commission has proposed the 'AccelerateEU' package to optimize fuel distribution across member states. In the United States, the sector has experienced varied outcomes, exemplified by the cessation of Spirit Airlines' operations following the failure to secure a $500 million federal bailout. Other North American carriers, including Delta and United, have adjusted their financial outlooks and pruned unprofitable routes to preserve margins in an environment where fuel prices are projected to remain elevated through 2027.

在全球範圍內，影響程度不一。歐盟委員會提出了 「AccelerateEU」方案，以優化成員國之間的燃料分銷。在美國，該產業經歷了不同的結果，例如 Spirit Airlines 在未能獲得 5 億美元聯邦紓困金後停止營運。其他北美航空公司，包括達美航空和聯合航空，則調整了財務預期並削減不盈利的航線，以便在燃料價格預計將維持高檔至 2027 年的環境中保留利潤。

While global capacity has decreased and pricing structures have shifted, UK authorities and major carriers maintain that summer travel schedules remain largely viable.

雖然全球運能減少且定價結構有所變動，但英國當局與主要航空公司仍維持認為夏季旅遊行程大致上可行。
