If Jet2 launched Bournemouth to Barcelona, Ryanair would simply offer all seats free until people get the message that Ryanair fares are the cheapest. Jet2 then would be painfully shown that to mess with Ryanair is a mistake.
Jet2 Edinburgh and Prague... thats what I heard just this morning... But wouldnt rule out other Spanish routes that Thomsonfly haven't got as they are the most profitable and successful pre-bookers.
