Lufthansa Strikes Cause Widespread Flight Cancellations

Lufthansa is experiencing widespread operational disruption as cabin crew members began a two-day strike on April 15, 2026. The industrial action, organized by the UFO union, follows a separate walkout by pilots earlier in the week, contributing to a period of significant travel chaos across Germany’s major aviation hubs.

The current strike by cabin crew is scheduled to take place on April 15 and April 16, 2026. According to the UFO union, the action affects all departures from Lufthansa’s primary hubs in Frankfurt and Munich. The walkout involves flight attendants from the airline’s mainline brand as well as Lufthansa CityLine, which manages short-haul services from Germany to various European destinations.

Sequential Industrial Action

The cabin crew strike immediately follows a strike by pilots represented by the Vereinigung Cockpit union. The pilots’ walkout occurred on April 13 and April 14, 2026, resulting in the cancellation of at least 700 flights. This disruption extended across several entities within the group, including Lufthansa, Lufthansa Cargo, Lufthansa CityLine and Eurowings, leaving tens of thousands of passengers stranded.

This wave of industrial action is part of a broader pattern of unrest. Both cabin crew and pilots engaged in strikes during February and March 2026, which also led to widespread cancellations. A cabin crew strike on April 10, 2026, caused significant turmoil, with the operator of Frankfurt Airport, Fraport, reporting approximately 580 flight cancellations by that Friday morning. Approximately 72,000 passengers across Germany faced travel disruptions during the April 10 action, which also saw CityLine cabin crew walk out at nine airports nationwide.

Labor Disputes and Management Response

The UFO union has attributed the current strikes to a deadlock in collective bargaining. Harry Jaeger, a chief negotiator for the UFO, criticized the airline’s approach to negotiations.

We are dealing here with an employer that has entrenched itself in a hardline position, while constantly proclaiming that it is ‘ready to negotiate at any time.’ Instead of seeking sustainable solutions, excuses are found—and, if necessary, fabricated—to justify worsened conditions and reject improvements.

Harry Jaeger, UFO chief negotiator

Jaeger further asserted that the employees had steered the company through difficult periods and contributed to its economic success despite challenging conditions and specific management decisions.

Lufthansa management has strongly condemned the industrial action. Lufthansa board member Michael Niggemann stated that the union is completely indifferent to the fate of our passengers and the future of Lufthansa. Similarly, Lufthansa brand chief Jens Ritter described the widespread strikes as completely disproportionate.

Operational Impact and International Warnings

To mitigate the impact of the current strikes, Lufthansa has stated it is attempting to utilize other airlines within the wider Lufthansa Group to operate some of the affected flights. However, the airline warned that massive disruption is still expected on April 15 and April 16.

The volatility of German air travel has prompted international responses. Romania issued an urgent travel warning for its citizens, citing the massive strikes and the resulting widespread cancellations and long delays across Germany.

Amidst the ongoing conflicts with the UFO and Vereinigung Cockpit unions, the company noted one positive development in labor relations: its newest subsidiary, Lufthansa City Airlines, successfully signed its inaugural labour agreement.
