ExxB: While your time and comfort are certainly worth something, this something is almost assuredly limited. As I indicated in my post, I would pay several thousand dollars to save a day or be fresh/comfortable, but I would not pay an additive of, say, $6000 on a transatlantic flight. I'd have the company pay for an extra night of hotel and food (maybe $400) plus Economy class rather than drop the extra $5600 on Business. My time and comfort (while worth a lot, especially to me) just aren't worth $5600 more.
