Clearly with such over capacity on Dub LCY , there won't be much in it for any 3 of the airlines . WX is very well established on the route ... So sf least they will get their fair share of the business. However, clearly BA marking out it's territory opposite Flybe.
BE have more to worry about here .
Interesting that BA came to the route only to abandon it mid season but that was 2008! A very different time ...
