The X-air services story began...
On 1 November 2009, Sabena technics and TNT
Airways formed a joint venture, X-air services,
whose main objective was to manage line & light maintenance
requirements of the airline's B737 and BAe146 fleets from Liège airport.
lts work has since been expanded to base maintenance, from Brussels
Airport.
As from 25 May 2016, TNT Airways has been renamed ASL Airlines Belgium.
