I think United is paying them a ton and has become a top partner: "We are constantly working to create industry-leading experiences for our customers. Twitter is a place where our customers engage with us 24/7 about a variety of aspects of travel. The new features that Twitter released have enabled us to create real-time engagements with customers to offer an array of services, from discovering where to go on their next trip, to answering common travel questions faster and easier. We’re excited to use these features to deliver additional experiences that connect people and unite the world through travel."
