After being grounded for four months by the COVID-19 pandemic, Sunclass Airlines (DK, Copenhagen Kastrup), formerly known as Thomas Cook Airlines Scandinavia, restarted operations on July 25, 2020.

The Danish leisure specialist, which was bought by a consortium consisting of Norwegian billionaire Petter Stordalen, Stockholm-based Altor, and London's TDR Capital after the collapse of Thomas Cook Group last year, currently flies to Palma de Mallorca and destinations in Greece from Gothenburg Landvetter, Stockholm Arlanda, Helsinki Vantaa, Billund, Copenhagen Kastrup, and Malmö. Flightradar24 ADS-B data indicates that the airline reactivated six out of its eight A321-200s, although they operate with a very low utilisation rate for the time being.

Sunclass Airlines' fleet of widebody aircraft, consisting of one A330-200 and three A330-300s, remains parked for now.

The carrier suspended all operations on March 20 and has only operated very few repatriation charters since then. Its restart was complicated by various levels of COVID-related restrictions in its Scandinavian base countries, in particular by the opposing strategies of Denmark and Norway with their relatively strict lockdown, and Sweden with one of the world's most lax regulations.
