Another option is actually search for Business Class fares and see if there may be combinations that offer reasonable fares. I am doing exactly that with Casablanca in September. When I first started my search a few weeks ago, the fares were over $4K, then $3405 with AC and LH. Today I just saw fares of $2550 with AC and LH. Once I am ready to book, $2550 looks reasonable to me.
