unfortunately you have taken my comment personally. It is a fact im afraid that GDP and Propensity to fly in Wales is low, (not the lowest in the UK though) and the CAA have just released information indicating that it is actually affluent people making more journeys rather than less well-off people starting to fly that is helping LCC prosper. Probably why Teeside remains a 1 aircraft base as well. Second homes owners account for a large number of low cost passengers too and in Wales, the number of second home owners abroad is not as substantial as in other areas.
Sorry if my comment caused offence.
