The cost of jet fuel has surged dramatically, doubling since the onset of the conflict in the Middle East, leading to widespread implications for airlines worldwide. EasyJet's country director for southern Europe, Javier Gándara, indicated that the situation is expected to worsen in the next three to four weeks, with no airline being immune to potential supply issues. Major airlines such as KLM and Air France have already announced fare increases, with KLM and Air France adding €100 (£87) to long-haul round trips. EasyJet has urged travelers to book flights early to avoid price increases as the summer approaches. Several airlines, including Aegean Airlines and AirAsia X, have suspended flights to the Middle East and cut services due to soaring fuel costs. Other carriers like American Airlines and Delta Air Lines have increased checked baggage fees significantly, while airlines like British Airways have hedged fuel costs to delay fare hikes. The situation remains fluid, with many airlines adjusting their operations and pricing strategies in response to the volatile fuel market.
