How to find the best airlines/flights out of Hongkong to Frankfurt in Business Class?

Hi All,

We are looking to make the best use of our Business Class flights to Frankfurt and trying to find information based on the flight numbers for the best airplanes - as A380, Dreamliner, refurbished A777 etc. Can someone point us in the right direction where to find those information all in one place or can recommend a good flight.
Many Thanks & Safe Travels
