The August webinar shaded light on the relationships among five associations. The associations are (in alphabetical order) the Air Transport Research Society (ATRS), the European Aviation Conference Institute (EACI), the German Aviation Research Society (GARS), the International Transportation Economics Association (ITEA), and the Symposium on Aviation Research (SOAR). Guest speakers are Martin Dresner from the University of Maryland for ATRS, Erik Verhoef from VU Amsterdam for ITEA, Gianmaria Martini from the University of Bergamo for SOAR, and I from The HK PolyU for EACI and GARS. Andrew Charlton from Aviation Advocacy was so kind to moderate the webinar.
