development
2 points:
1st - all financial data is available on MAG's website. Download the report and accounts and u'll see that BOH don't make much money from non-aeronautical interests. The aeronautical revenue is slipping too - but this is in line with increased LCC activity. 07/08 report and accounts due out soon. Latest one shows BOH is in the black.
2nd - master plan at BOH gives all details of development at the airport up to 2030. Unfortunately no high-speed run-offs or parallel taxi-ways, only re-aligned ones and improvements to aprobn areas etc. This can be downloaded from BOH's website.
