A global kerosene shortage is driving up airline ticket prices across Europe, prompting Dutch carrier KLM to cancel 160 flights next month on routes including London and Düsseldorf. Aviation economist Wouter Dewulf of the University of Antwerp warns that fares will continue to rise in the coming weeks, particularly if the conflict in the Middle East remains unresolved, and advises travellers to book as soon as possible. While Belgium is relatively well-supplied through its position on the NATO fuel pipeline connecting Brussels and Liège airports to ports in Antwerp, Rotterdam, and Le Havre, broader European stocks are estimated at only around six weeks' supply — though Dewulf expects popular summer holiday flights in July, August, and September to remain largely unaffected, as those are the most profitable routes airlines are unlikely to cancel.
