KRK is not sustainable with both easyJet, Ryanair direct and Wizz dropping off a few miles up the road.
I'm struggling to see a need for 10/11 flights a day to LGW too.
EasyJet won't give up LGW easily and Ryanair already know that as previous attempts to compete there were no great success. I can see BHD making a play for some easyJet work as their 319s can operate effectively there as already proven a few years ago.
In the short term there'll be a load of loss leading fares but that will be followed by rationalisation on several routes. I'll not be flying Ryanair at any price. Been there, done it, didn't like it for a multitude of reasons. We are already blessed with a multitude of choice to many destinations and they're unlike to miss my £29.99.
