no idea at all, but I recently used points combined with an expensive coach ticket (Grr) and flew business first on continental from ewr to amsterdam and then airfrance business class from paris back to ewr.

Business first was simply awesome. business class on air france kind of sucked. it wasn't that great at all. I flew coach twice last year from iah to cdg and that wasn't much worse. (or rather business wasn't that much better)
