Aegean has never taken Gatwick seriously. They're forever chopping and changing it. Some days in some weeks they fly and then out of the blue it can disappear. They promised a daily schedule for next summer... but now that's gone. They could even connect SKG with LGW to offer at least one direct connection with London from there like Olympic used to do. The south east is also is also the most populated part of the UK and Gatwick would certainly be my "go to" UK airport if I could rely on it.
