Brussels Airport has asked all carriers to **pre-emptively cancel around 50 % of departing passenger flights scheduled for 12 May**, warning that security-screening, ground-handling and some air-traffic support staff are expected to join a national trade-union demonstration in Brussels. A bulletin on the airport’s website – echoed by multiple media outlets – stresses that proactive cuts are needed to keep queues at immigration and security under control and to avoid unsafe crowding in the terminal.
The walk-out, organised by Belgium’s three largest union confederations (ACV/CSC, ABVV/FGTB and ACLVB/CGSLB), is aimed at government pension reforms but will inevitably hit aviation.
The action would be the **ninth strike-related disruption at Brussels Airport since early 2025**, underlining the fragile labour relations climate that mobility managers and travel buyers have faced for more than a year.
Unlike full shutdowns seen on 12 March and 29 April 2025, the airport hopes to keep “just under half” of outbound flights operating and expects limited impact on arrivals.
Airlines have begun re-protecting passengers; codeshare partners are pooling capacity on larger aircraft, while Brussels Airlines says it will prioritise routes with high business traffic such as Frankfurt and London.

If changing itineraries means rerouting through adjacent Schengen hubs or adding last-minute stops outside Belgium, VisaHQ can fast-track any required visas or transit permits. Their platform (https://www.visahq.com/belgium/) gives travelers instant visibility on documentation rules and offers expedited processing—particularly useful when industrial action forces sudden schedule shifts.
For corporate travel teams the advice is clear: **avoid same-day departures on 12 May, build extra buffer time for connections, and check that negotiated fares allow penalty-free changes**.
Mobility specialists should also monitor SNCB and De Lijn updates as rail and bus services to the airport are likely to be disrupted.
Looking ahead, the recurrence of strikes may prompt multinational employers to reassess Brussels as a regional hub for assignment travel.
Some firms are already diverting intra-EU shuttles to Amsterdam or Düsseldorf on peak protest days, while others are considering hybrid work solutions to cut in-person meetings that coincide with known strike calendars.
