LTNman - don't feel the need to apologise, I think your comment abput FR at STN is pretty fair. Yes most airports have a dominant carrier but when the airport acts as a true hub for the airline, the airline is limited in its recourse if unhappy. Pan-Europe LCCs don't have hubs so have much greater capacity to move aircraft as they wish. I can't think of many large airports in Europe where just one LCC (rather than network airline) has such a high proportion of an airport's traffic.
In a few years time London airport slots will become scarce but right now I think FR have the upper hand over MAG at STN
