I personally really really want to see services to Abu Dhabi/Dubai (Etihad/Emirates) and/or Istanbul (Turkish Airlines) for
world-wide connections. I don't fly on KLM via AMS - they never have good connections to Asia or the Far-East and air-fares tend to be way too high. BOH has the potential to offer this to people in the local area, not even BRS can do that with their runway limitation. That's assuming Emirates and Turkish would ever be interested in doing it hahaha. I doubt they would, given our own proximity to LHR.
Irish Cream, you're brave starting a SOU v BOH post
It would probably be better for the two airports to work together somehow to ensure both survive... One example of this could be the sharing ground handling staffing/equipment or even a shared/consolidated remote air-traffic control team etc etc?
