Never mind, I remember well the redundancies at Luton when Ryanair and TNT left for the BAA buck!
When Stansted is sold off it might happen again. As can be seen Gatwick is taking Stansted traffic so Luton could become a target of Stansted again, which is what competition is all about.
Even all those year ago if Stansted offered nothing to Ryanair to move bases the airline would still have ended up at Stansted, as they outgrew small Luton the same way as easyjet outgrew Luton.
