Airlines are trimming summer schedules as jet fuel shortages loom across Europe. Lufthansa has already cut nearly 20,000 flights over the next six months, warning that fuel could run low as soon as next month. Sky-high fuel costs linked to the war in Iran are driving the crunch, leaving travelers facing higher prices and fewer options for European vacations. The German carrier's drastic move signals how serious the situation has become for the industry.

The fuel squeeze threatens to make what was already an expensive travel season even costlier for consumers. Airlines face an impossible choice: reduce service to conserve fuel or pass eye-watering fuel costs directly to passengers through higher ticket prices. European destinations that rely heavily on air connectivity could see reduced tourism as carriers are forced to prioritize only their most profitable routes.

Travelers planning summer trips to Europe should prepare for sticker shock and limited availability. Industry experts are warning that the situation could create a "total mess" for vacation planning, with popular routes selling out quickly and prices climbing even further as the peak summer season approaches.
