My .02 - I travel business class on my own dime. Dont specifically stick to one airline since I am looking for the best deals. Have tried checking with multiple so-called business class discounters...but either the savings are not worth it, OR the risk of getting airlines to cancel your flights is too much. Have saved considerable amounts setting flight alerts on skyscanner/justfly and using momondo. Flexiblity with dates, airports are key to finding better rates on business class flights. You just have to be careful about the layover information.
