Just used Flight Club for the first time and all I can say is wow! An agent who was willing to help me change flights for an upcoming work trip where I needed to be home a day earlier than originally planned. No issues over finding space and with relative ease I was moved to the flight of my choice. The fact that there was a significant reduction in fare difference between doing it online (excluding the fee of course) and what I ended up paying made me even happier. I will absolutely keep that in mind for the future as other airlines would have charged through the nose for a small change like that
