I had flown BF to europe several times before I ever saw the concierge or someone who introduced himself as such (there may have been one before and I just didn't notice). The first time I saw one and saw him talking to some of the other PAX he clearly he seemed to be arranging airport transportation for them. I sort of said, oh, I didn't know such a service was available. He seemed to be not that forthcoming and either he asked or I volunteered that I had upgraded using miles for the BF seat and that seemed to imply that such services were not available to me. It may be that he didn't say that, but this was the impression I got from the interaction. Are the concierge's just for PAX who are not using miles in some way? I wasn't in a total award seat but had paid the higher coach fare plus miles to upgrade (which I usually do).
