A MarketTools survey focusing on customer satisfaction with US airline carriers indicates that although US travelers may be embracing social networks to express feedback more frequently than in the past, social media as a feedback or customer service channel is still nascent. Many travelers are using social networks to let their friends and followers in on their travel woes. In fact, the MarketTools survey indicates one out of 10 US travelers has used social media to complain about an airline. Because the complaints are undirected though, they often go unanswered. The survey shows that only one out of four consumers who complained via social media got a response back from an airline. Although travelers are voicing dissatisfaction to their friends via social media, few travelers actually use sites such as Twitter and Facebook to give direct negative feedback to airlines. Only 2% of travelers who had given feedback or complaints about airline service in the past year said they had done so via social media. Most travelers reached out to the airline customer service department through the website, email or phone. Get the full story at eMarketer
