Fifteen flights were cancelled and several others delayed at Charleroi Airport due to a strike by air traffic controllers at Skeyes. The strike began on Monday evening under air traffic controllers in Liège and Charleroi, according to Skeyes. Other departments of the company also announced that they would stop work between 02.30 and 07.00 hours on the night of Monday to Tuesday, which caused delays in the morning. The strike follows negotiations held earlier on Monday with trade unions over a digital control center in Namur. In that city in Wallonia, the first digital air traffic control tower in the country will be built, where flights to and from Charleroi and Liège airports will be coordinated. At Brussels Airport, about 25 flights are departing later than planned, while in Liège, about 20 flights are affected, according to spokespeople for the airports and air traffic controllers. The strike has consequences for flights to and from Charleroi, and the situation is currently being monitored by the airports and air traffic controllers.
