The deal follows a 2013 marketing agreement in which Expedia Inc’s technology powered platforms for Travelocity’s U.S. and Canadian websites, while Travelocity drove additional web traffic to Expedia. The merger marks further consolidation in the online booking space, which has seen a number of acquisitions from Expedia Inc’s main competitor, The Priceline Group (PCLN.O), including its $2.6 billion takeover of restaurant reservation website OpenTable last year.
