What you say about the drop off charge may be correct, but I don't like it & sympathise with those others who don't like it, either. It may very well be a consequence of getting a low fare; if it is, that is highly regrettable.
I don't agree with you on BOH being likely to disappear as a business, though. It was there , without pax services, for many years; why should the loss of some of its business now threaten its very survival ? It's not good, but may not be fatal. There are a lot of other, non-airline businesses based there.
