Spanish low-cost airline Volotea has faced controversy for asking customers who already purchased their tickets to pay an additional surcharge to cover the change in fuel costs. The airline's policy allows it to adjust ticket prices in the event of "extraordinary" changes in fuel prices. This move has sparked outcry among passengers and speculation about other airlines in Europe and other parts of the world adopting similar policies. The cost of oil and jet fuel has increased significantly since the U.S.-Israeli strike on Iran, leading to increased surcharges for airlines like Alaska Airlines and JetBlue.
