It was I who suggested that the 8,650' runway length might be too short, but I'm not a CX person, so it's really intended as a question; does CX have a minimum for 74F operations?
If it's a question of adding 1500' of concrete (which should have been done years ago anyway), that can be done, but if at all possible, what I'd like to know is whether DUB has been considered and if so, was/is the fact that the runway is too short a significant factor or worse still, a "deal breaker".
There have been rumours - but just rumours in the past - that other carriers have rejected DUB due to runway length (EVA among them), but if we could get some confirmation that it is causing a problem ...
