Rudi - I think that Swissair would be a very welcome addition to the oneworld alliance. Before moving to the US I flew with Swissair regularly (and they brought us here) - roughly one Swissair flight every month for me/my partner. It would have been great if I could have put those miles into my BA account. And I would have felt less guilty about using (cheaper) Swissair for my LHR-Geneva flights, instead of BA!
