LGW_08R; you make some valid points here about Ryanair and LGW, however, I think Ryanair will be quite comfortable with Easyjets efforts to keep Aer Lingus in a Corner!
However, I can see that Ryanair will do a Knock style approach to Aer Lingus on markets where they compete, eg Gatwick Eindhoven, I can see Ryanair increasing frequency and lowering fares on Stansted Eindhoven to ensure Aer Lingus suffer for loads and yield. They may have increased frequency already but I am not sure.
