Boys running an airport you constantly have to 'balance' lots of things. Easyjet got a load of publicity them selves for the TFS, now if the airport was seen to be rubbing other noses in it!! i.e. other operators who already fly to TFS.....
As for the new DUB flights well every one has a timetable to run to and its not up to the airport to go against such things. Has EI publicly announced it?? Your average Joe public won't know the flights were in the 'system'!!
Purely my thoughts.......
