Airflow constraint at Hamburg Airport, specifically regarding kerosene supply

Hamburg Airport, one of Germany's busiest airports, is currently facing a jet fuel shortage due to a temporary reduction in production at the Heide refinery. This unexpected supply difficulty has led to flight delays, cancellations, and changes in schedules, including some flights to Mallorca being rerouted.

The maintenance period at the Heide refinery, known as a TÜV shutdown, started on Monday, September 21, 2025, and is expected to last until October 4. Airlines and suppliers are actively seeking solutions to the jet fuel shortage, but organizing short-term alternatives proves challenging.

The German air traffic control agency has issued a NOTAM (Notice to Airmen) regarding the unavailability of jet fuel at Hamburg Airport. Airlines have been advised to contact their suppliers and operators to coordinate return fueling if possible.

Passengers are encouraged to monitor their flight status closely as delays and changes in flight schedules are imminent. The economic damages for Hamburg Airport due to the jet fuel shortage are currently indeterminable.

The disruption in jet fuel supply is a rare event, demonstrating the vulnerability of infrastructure in highly developed markets. Hamburg Airport has warned of possible impacts on flight schedules due to the jet fuel shortage, and some aircraft may have to start with additional refueling stops at other airports or be rerouted.

The fuel shortage is expected to last from September 18, 2025, 02:00 GMT (04:00 CEST) to October 17, 2025, 12:00 GMT (14:00 CEST EST). As the situation evolves, it is essential for passengers and airlines to stay informed and adapt to any changes in their travel plans.
