As it looks, Sky Services is history at LIQS. The airport is currently closed. Nobody knows who will take over the operation of the airfield.
In 2015, Sky Service won the tender to operate the airport, against Delta Aerotaxi. Seems like Delta went to court and in May, the court has decided that they have won the tender under false pretenses, namely an underestimation of the costs of renovating the airport and an overestimation of the possible yields. Normal business I would say.
