Wow, a dozen posts just while I was typing my first post! Let me expand a little. The PAX paid for/earned a BF seat therefore they can do what they want with it within company policy. Switching 3 or 4 times would be too much but one switch would be within policy.

So what if the spouse comes up and drinks? Even 10 drinks probably cost CO very little but the money made from a positive customer experience would pay them back in dividends. Sheesh. I could go on but I need to calm down.

Oh, and one more thing, visiting in BF/FC is generally frowned upon. If you'd like to visit, main cabin is more appropriate.
