It's clear that knock has a good relationship with ryanair and they operate some routes from both airports .it's clear that the uk and holiday routes are very successful and remains to be seen how the euro routes will perform.
In my opinion I would say it would be just the euro routes bar maybe Frankfurt that fr would move to Shannon if any at all. If dusseldorf performs well for lufthansa I would be hopeful of a few other german cities being added for 2013.
If ryanair return to Shannon with all the uk regionals aer lingus regional would be screwed .
I hope we can get a Malaga and palma route for 2013 before Shannon does should ryanair start to expand again from snn.
