I'd tend to go with the Idea of wait and see with things like security queues. It's not that many years ago before T2 in particular DUB was a disaster for security queues, and I'm talking regardless of destination as opposed to arrival security. I flew STN to BFS some weeks back and queued for about 45 mins and saw the most appalling, rude and unprofessional security I've ever seen and really quite racist - it made me so proud of our guys on the outbound at BFS and I'd say same of BHD. It can be slow doing things like immigration at small airports, but it can also be much quicker, it's down to them how much of a success they want to make of this.
