It boggles my mind this has never been done before, but why wouldn't UA/CO put a BF seat in the airport lobbies at each of their hubs? Many more people would be more likely to spend some cash on a BF seat if they got to try it out, like when you go to Brookstone you get to try one of their massage chairs. A few years ago, on my young and gullible years, I upgraded on PEK-EWR because I had a last minute B fare (no copay for a B fare at that time). And when I called to upgrade, I was still unsure if I should burn 25k miles to move up to BF. All I had seen at that point were the FC seats on domestic aircraft, and they were nice, but when you are 25 and dumb, you think "eh I can handle it". Curiosity and jet lag got the best of me, and I pulled the trigger. Well, when I pushed the seat buttons and the seat just kept on reclining and reclining, it felt like the moment when I first took off the training wheels off my bike when I was 7 or so. I had NO idea those damn things went all the way to flat. It was like being a kid all over again. I don't care how many adds they put up, or how many posters they print showing lie flat seats. Until you try one out, you really have no idea how bitching those seats are.
