Like a lot of these airport threads everyone seems fixated with Self Loading Cargo. The largest airline to operate out of BOH during the winter is Atlantic Airlines. Freight nevers gets mentioned. Must be a good earner for the airport. Then there is GA, both puddle jumpers and Biz. When ever I visit BOH there always seems to be a steady amount of GA traffic. Oh and Chobham / FRA again large fleet based at BOH. What about European with all their aircraft conversion and maintenance. Etc etc. BOH will always survive due to it's diverse activities. Might not be as sexy as being to quote nice big pax numbers, but Freight, maintenance and GA are more important to BOH than a few extra pax flights.
