Since ZRH is LX's hub with ample possibilities to swap the damaged aircraft with a new one you certainly have a case to plead. Just send the matter with the correct documentation to the CAA using the info here: http://www.caa.co.uk/default.aspx?ca...90&pageid=6480

You could also approach the swiss enforcer BAZL using the english form on their german webpage:

BTW, you get to keep the miles even if LX has to pay on the directive of CAA or BAZL.
