Hello,
For those that are interested, here's a chart of the number of passengers flying Cork - London over the last 25 years (CAA data).
Over 250,000 more people flew in 2004 than last year, but that was back when Easyjet entered the market and Ryanair responded by adding a lot of capacity. As we can see, that wasn't a sustainable level of capacity. Since 2010, the number of people flying has been relatively flat at just below 800,000 per year. This doesn't reflect the level of growth seen in both the Irish and UK markets recently, so I would suggest that the market does have scope for some growth. However, Ryanair have increased frequencies on ORK-STN compared to last year. The usual story is a brief win for customers until the balance of supply and demand returns.
