Ryanair face competition on 5 of their 6 Basel routes.
LONDON - Easyjet, British Airways, Swiss
CAGLIARI - Easyjet
PORTO - Easyjet
ALICANTE - Easyjet
MARSEILLE - Twin Jet
STOCKHOLM - n/a
Their competitors are obviously delighted with the news that [1] Ryanair are leaving Basel, and the consequent [2] Ryanair will not be expanding at Basel.
I think Ryanair could have successfully launched routes (from bases and doing W's) to Pisa, Venice Treviso, Bologna, Bratislava, Bremen, Brussels Charleroi, Eindhoven, Edinburgh, Girona/Reus, Zadar - to name but a few. So in a way it's a shame to see them leave a airport where there is so much potential for expansion. But I'm sure many are saying good riddance.
