By introducing say a 3 times daily LGW NQY service, Flybe would seriously undermine WOW on their core route and this could potentially have implications for PLH airport. That maybe Flybe's reasoning for looking at NQY LGW, and possibly for considering LGW EXT, if that is infact true.
Here is the article in the Western Morning News.
my own personal thought would be that it would go to Aberdeen perhaps x2 daily and if they are going to do LGW-NQY i would of thought that they would dip a toe in the water at x1 daily and see how it goes.
