I have given up on the F experience on VX, due to the same issues brought up here. After the 4th paid upgrade with the fast, furious, and disappearing service, I found myself happier in MCS, where I see the FA's more often. I have given much of my UA business to VX, but I have seen an improvement on the UA side regarding attitude and service. I hope VX FA's can learn that "better than the competition" customer service, especially in F, wins customer loyalty.
