Brussels Airlines NV will move 15 aircraft out of its home city in order to resume flights after authorities said that Tuesday’s terrorist attacks will shut Belgium’s main hub airport until the weekend. The carrier will relocate 10 Airbus Group SE A320-series planes to Liege, 60 miles (97 km) to the east, and five BAE Systems Plc Avro RJ100 regional jets to Antwerp, 30 miles north. Its Brussels Zaventem base will stay closed through Friday at least as investigators probe explosions that killed 11 people. Brussels Air plans to operate 64 flights to or from its makeshift hubs on Thursday and 96 on Friday, and said in a statement Wednesday that the changes will stay in place until Zaventem reopens. The carrier is also sending five empty jets to Africa to fly out passengers stranded by the bombings. Even with the emergency schedule in place, the majority of Brussels Air’s 50 aircraft will remain grounded in the run up to Easter, one of the busiest travel periods of the year, preventing it from operating a full timetable that usually comprises about 250 flights a day. Ryanair Flights The move comes after Ryanair Holdings Plc, the biggest foreign carrier at Zaventem, focused all Belgian services on its hub at Charleroi, or Brussels South, some 35 miles from the city, helping to maintain air links between the capital and the outside world. Brussels Air still needs temporary bases for its A330 long-haul aircraft, which require longer runways and may need to be moved abroad, complicating traffic rights. The carrier is speaking with airports in Germany, France and the Netherlands, spokesman Geert Sciot said, while declining to identify them. With the airline 45 percent owned by Deutsche Lufthansa AG, an agreement involving a German hub may be likely, though even at Frankfurt, with its four runways, optimum operating slots will be at a premium as Easter approaches. Ryanair rival EasyJet Plc said Wednesday it was moving its Zaventem flights to Lille in northern France, from where there are good rail links with Brussels. TUI AG’s Belgian arm Jetairfly will divert some planes scheduled for Zaventem to Charleroi, where it already operates, and Ostend in the north. Charleroi is also served by Wizz Air Holdings Plc—Eastern Europe’s biggest low-cost carrier—Turkish discount specialist Pegasus Airlines, and Thomas Cook Group Plc, which plans to divert its Zaventem flights to Liege.
