The European Commission decided on 5 July 2021 to open an in-depth investigation into the restructuring plan of the airline TAROM notified by Romania in May 2021, as well as into the EUR 190 million aid to support it under the Guidelines on State aid for rescuing and restructuring undertakings in difficulty.

The Romanian airline TAROM has been in financial difficulties for many years. In February 2020, the Commission approved rescue aid of EUR 36.7 million in favour of the airline in the context of a Romanian notification.

Swissport Belgium, one of the two licensed ground handling service providers at Brussels Airport, was declared bankrupt in June 2020, three months after the airport's operations were interrupted due to measures adopted by the Belgian government to limit the spread of COVID-19. Nearly 1,500 workers lost their jobs.

In order to support these workers, Belgium applied for assistance from the European Globalisation Adjustment Fund (EGF) to help these redundant workers back into employment (especially those with no professional qualifications or with a low level of education).

Thomas Cook Belgium and Brussels Airlines may escape fines from the Belgian Competition Authority (BCA) notwithstanding the conclusion of an agreement providing for anticompetitive practices according to the Investigation and Prosecution Service of the Authority.

In August 2017, the BCA had opened an investigation into potential anticompetitive practices resulting from the conclusion of a "Commercial Service Agreement" between Thomas Cook Belgium and Brussels Airlines.
