This study provides insight into how aviation and non-aviation factors affect the decision to suspend air routes. Using examples from Australian domestic routes, the paper analyses the business relationships and negotiation processes followed by airports, airlines, and destination management organizations (DMOs) to avoid air route suspensions. Data were collected through semi-structured interviews with key aviation and tourism stakeholders directly impacted by suspended routes. The outcomes of this paper demonstrate that while most of the major reasons for air route suspension in Australia are mentioned in existing literature and are linked to demand, other factors have not previously been deeply investigated, including how stakeholders can be involved to avoid air route suspension. The paper also explores and identifies strengths and weaknesses in the relationship among airlines, DMOs and airports.
