This is such a shame, however not suprising. WW cannot beat FR on brand recognition abroad. Therefore WW relies on PAX originating from the UK. FR has the power of marketing europe wide - so if they start a route thats in competition with WW - like PRG/AGP/ALC/PMI for example, locals who want to get to the UK midlands will know more of FR due to their size compared to WW.
As I say, it is a shame, as WW offer a good service 9 times out of 10. However, recently looking at PRG from BHX, FR are offering £10 flights whereas WW offers £24.99 one way...I wonder who will win.
