Online travel agents (OTAs) act as double-sided platforms within the travel space, consolidating inventory from travel suppliers and facilitating its marketing, distribution and sale to travellers in return for a commission (O’Connor, 2009). As platforms, OTAs add value for all participants in their ecosystem. On one side are suppliers who gain visibility with customers and markets otherwise difficult to access. On the other sit customers, who can access a broader, multi-brand, selection of travel products and services than they might be able to identify independently (O’Connor, 2016). This value grows with network size, with the overall utility of the platform increasing depending on the number of products listed and customers addressed.
