Thanks once again for your comments - it's always good to have a discussion with someone who is up on the rules!
I had tried the option of going direct BUD-IST on TK - but I have to travel on a Saturday and this is the only day there is no TK flight (hence going via ZRH)!
Although as I mentioned we are still waitlisted for two sectors, so we may not be going anyway...
Just out of interest - and this is in relation to one of the other threads about awards on code-shares - I was advised by Qualiflyer that there is no award availability on the Malaysia Airlines service from Zurich to Kuala Lumpur (at least in First). I didn't push the point as I wanted to fly Swiss with the beds, but it would be interesting to know for future reference if the information I was given is correct.
Regards
