While I appreciate your interest in such details, I believe we should also be realistic in how precise such trade-offs can be made. Eg. the IAOC just doesn't have the staff or budget to create detailed models on the cost/benefit analysis and the IAOC would easily end up in a situation where more money/energy gets spend to try to determine the optimum site location and to fully inform the community on every decision it makes. Basically, what I expect the IAOC to do is to make a judgement call based on the various variables. So far, I don't believe there is any evidence that IAOC has made decisions to hold meetings in places that are completely out of the question. At the same time, by occasionally holding a meeting in a location that is somewhat unusual, we will continue to be able to evaluate whether all our assumptions about the importance of airline hubs or the desirability of a short train trip are really that important for all participants. Basically, instead of endless discussions on the merits of a required short railtrip from 1 of 3 different very large airports that are all listed very high in the european top 10 hub airports, let's go to Maastricht and see how it will work out.
