Absolutely Refuellerman.
Passing through tonight the airport packed to the gunnels. It really does need more space or re-planning for peak summer. Great to see it doing so well and I agree with the points about people seemingly using a Belfast airport over Dublin. Still a lot of myths about pre-clearance and how much time it really saves and people who don't even know Norwegian fly transatlantic from BFS despite every possible communication channel being tapped.
On the point of future growth I see no reason why Norwegian won't offer more and possibly utilise the aircraft currently layed up for several hours on the ground during the day.
