Has anyone had any luck booking business class saver to europe? It seems like every year I try to book a vacation to europe from SFO and business class saver is never available on any dates no matter how far in advance I try to book. Has anyone had any luck with this? I'm trying to get to Istanbul but I'd settle for just getting to a UA european hub and buying tickets directly to IST.
Being 1K hasn't seemed to help me either.

Any suggestions are welcome.
