babemagnet - 2500 people for a relatively small airport which is mainly used for Dutch and Germans to go on holiday and with *relatively* little inbound local tourism sounds on the high side, even when you include all the local economic benefits. I would be surprised if there are many hotels / restaurants around Weeze seeing *substantial* amounts of trade from inbound tourists. Sure, there are jobs that depend on Weeze, but I imagine most are direct jobs (e.g. firecrew or people working at shops in the airport) rather than indirect.
I imagine that the main business trade goes through Dusseldorf's main airport (or FRA) rather than NRN. I guess cargo would mainly head for the much larger FRA, AMS, CGN or LGG. As for tourism, I haven't seen many ads for '2 weeks in the sunny Ruhr !
