I was seated in one of the premium rows earlier this month (right behind first class -- complimentary with CO *G) and the FA came over and told all six of us that the Direct TV was free. She told us that we needed to swipe a CC to activate the system but that it would not be charged. I, along with the woman in the middle seat, took advantage of this nice offer.
Now, two weeks later, I am waiting for a response from CO customer service since my credit card was charged. I'm glad to see that other people have heard of this though, since I was afraid that perhaps my story of only one FA might not be believed by the folks answering requests.
In short, I have heard this firsthand (for any premium row) but was charged anyway. Once I get a response from Continental I'll post it here.
