Over the past few years, the research team has established advanced contacts with airlines, airports and slot coordination entities. Recent instances include the 138
th Schedule Coordination Conference (Hamburg, Germany, June 2016) and a recent meeting promoted by the International Transport Forum at the Organization for Economic Co-operation and Development (OECD) on “Capacity Building through Efficient Use of Existing Airport Infrastructure” (Queretaro, Mexico, March 2017). These contacts will help us to establish contacts with the stakeholders to interview.
