Easy tried bhd and found no commercial advantage though that means nothing as times change and it was only the luton flights at the end of the day.
There are a couple of ezy flights at bfs that would go past the curfew time at bhd and quite often delayed flights too, but again that doesn't mean a lot.
As for the dub/bhd purchase would it not be more of an advantage if the daa bought bfs ? No restrictions, 24/7 operations, plenty of runway and capacity to expand. Don't shoot me down but is Dub almost at capacity? I don't know.
Looking to the future would it be viable to move all cargo operations to bfs get the railway sorted there and move freight around by rail and road. Would it free some capacity up at dub? I don't know how big the freight operation is at dublin but I'd guess it's pretty big. I know there would be huge costs involved and I'm probably talking rubbish, it's just a thought.
