ASL Airlines Belgium, (ASLB) formerly TNT Airways, is a Belgian cargo airline operating chartered flights mainly to European destinations. It has its head office and hub on the grounds of Liège Airport. The airline was originally a subsidiary of TNT Express but was acquired by ASL Aviation Holdings and rebranded in 2016. ASL Aviation Holdings DAC, the parent company of ASL Airlines Belgium, is headquartered in Swords, County Dublin, Ireland.
ASLB operates worldwide Boeing 737 freighter services under the ASL Aviation Holdings brand and for major express integrator and e-commerce customers including FedEx and Alibaba. In addition to its own fleet, the airline also manages various third-party airlines providing aircraft for FedEx's European network.
TNT Express was established in Australia in 1947 by Ken Thomas. The company expanded from a single truck to road and rail freight services across Australia including, for the first time, new overnight services. In 1958, the company became known as Thomas Nationwide Transport or TNT for short and, by 1961, TNT was listed on the Australian Securities Exchange.
The company was founded in 1999 as TNT Airways S.A. Air freight operations began from Liège Airport. TNT Airways started flying with BAe 146-300 and Airbus A300. This transformation brought the company to an extension from a European to a Worldwide coverage. The Group introduced their first Boeing 737-300 in 2003.
In May 2004, TNT Post Group (TPG) announced major expansion of the TNT Express European air hub in Liège, Belgium. To consolidate and improve recognition of the TNT brand, the name 'TPG' was dropped in favor of 'TNT' in 2005.
The split-up of TNT N.V. which was announced in December 2010, materialized in May 2011 when TNT Express and TNT Post (now: PostNL) were separately listed on the Amsterdam Stock Exchange.
In May 2016, ASL Aviation Holdings acquired TNT Airways, joining the ASL portfolio of nine other airlines in Europe, South Africa and Asia. Rebranded ASL Airlines Belgium, the airline signed a multi-year service agreement with the new Fedex/TNT combination.
As of November 2021, ASL Airlines Belgium serves six scheduled destinations in North America and China under its own brand name with several dozen more operated as contracted charters, e. g. on behalf of DHL.



As of October 2025[update], ASL Airlines Belgium operates the following aircraft:
