"We welcome more than 20 million guests on board every year and we are thrilled to be the first Canadian airline to respond to their needs around the clock on social media," said Greg Hounslow, WestJet Manager, Emerging Media. "Guest care has been at the core of WestJet's success since the beginning and we made this further investment in our social presence to continue to meet the evolving needs of our guests. With our international expansion it is critical to be available to provide customer service on time-sensitive issues outside of a nine-to-five world."
