I believe the newspaper has got the wrong end of the stick with this report. All easyJet holiday flights operate using existing seats on the scheduled flights.
The only charter flights that exist are those to Lapland- Santa charters at winter and a route between BFS and Verona that has operated between mid jan and end of feb. These exceptions are due to a couple of travel agents/tour operators chartering the whole aircraft and only operate in quiet months.
I could be wrong but doubt that LPL airport are about to start their own travel agency selling seats on new easyJet charter only flights on to destinations that are already served on easyJet and scheduled flights from Liverpool.
It's much more likely that it is some sort of advertising or marketing campaign for passengers to use easyJet holidays for their holidays by travelling on the existing flights
