Brussels Airport Operations Resume After Aviapartner Strike

Brussels Airport returned to normal operations on Tuesday morning after a spontaneous strike by ground handling staff at Aviapartner brought check-in and boarding to a standstill for much of Monday. All Aviapartner employees have returned to work, and registration and boarding for affected flights are proceeding normally, the airport announced.

What Happened

The wildcat strike began in the early hours of Monday, June 15, when Aviapartner check-in and boarding staff walked off the job without prior notice or union authorization. The action disrupted approximately 60 flights operated by airlines served by Aviapartner — including TUI fly, Ryanair, Iberia, and British Airways — causing delays of one to three hours. No flights were cancelled.

Crucially, flights handled by Alyzia, the other ground handler at Brussels Airport, were not affected. Baggage handling and arriving flights also continued as normal.

By Monday evening, union leader Hans Elsen (ACV) indicated the strike would likely not continue into Tuesday. That prediction proved accurate: Brussels Airport confirmed Tuesday morning that all Aviapartner staff had returned to work.

Root Causes: Pay and Recognition

The strike was triggered by long-standing employee frustration over a new remuneration system introduced “without prior social consultation,” according to unions representing the workers — Synova, ACV Puls (CNE), and BBTK (Setca).

Jorn Hanssens of ACV Plus explained the depth of the dissatisfaction: “This spontaneous strike is about long-standing dissatisfaction regarding staff policy. People who have been working there for years and have built up experience and knowledge still earn the same as a starter. That dissatisfaction runs deep, because at rival companies, those people are recognised with a slightly higher pay scale.”

In a joint statement, the unions said employees “do not feel sufficiently heard, valued, or involved” — a sentiment they described as particularly striking given the workforce’s typical loyalty. “When such workers, known for their loyalty to their job, feel the need to take action, it shows the degree of frustration,” they noted.

Broader Context: A Strained Aviation Sector

This strike comes just two weeks after a far larger disruption: on June 2, an unscheduled strike by Skeyes, Belgium’s air traffic control agency, brought all air traffic to and from Belgium to a standstill, causing nearly 140 flight cancellations at Brussels Airport.

The back-to-back labor actions highlight mounting tensions in Belgium’s aviation sector. Workers across multiple segments of the industry — from air traffic control to ground handling — are using strike action to press grievances about pay, working conditions, and management practices.

The Aviapartner strike also unfolded against a backdrop of broader social unrest in Belgium. On the same day operations returned to normal at the airport, over 10,000 people gathered in Namur for a major interprofessional demonstration protesting budget cuts.

What Comes Next

A conciliation meeting between Aviapartner management and the unions was scheduled for Tuesday morning at the SPF Employment, Labor and Social Concertation. The outcome of these talks will be critical in determining whether the underlying grievances — particularly around pay equity and worker consultation — can be resolved without further disruption.

For passengers, the immediate crisis has passed. However, the pattern of spontaneous labor actions in Belgium’s aviation sector suggests that unresolved tensions could lead to further disruptions in the weeks ahead. Travelers flying through Brussels Airport are advised to monitor their flight status, particularly during peak summer travel and the ongoing 2026 FIFA World Cup.

Analysis

The Aviapartner strike, while brief, is significant for what it reveals about labor relations in Belgian aviation. The fact that workers described by their own unions as “loyal” engaged in an unauthorized wildcat strike signals deep-seated frustration that has not been adequately addressed through normal channels. The company, which operates at 72 airports across six European countries and South Africa, now faces pressure to revise its remuneration policies or risk further erosion of workforce morale at a time when the aviation industry can ill afford additional disruptions.
