They would be crucified by Ryanair. Every route they went on Ryanair would do double the frequency for half the price. The London route tho might be an option, as you pointed out they are strong in London so they could do well on that. They could do that as a starting point and see how it goes but I dont think in this environment they would try it, they didnt have the nerve in the good auld days when they flew to ORK/NOC/SNN so I doubt they will now.
