Apologies for posting here rather than OW forum but I am looking for a quick response.

Is there any fare search website that can get me the cheapest OW business fare? I can check each individual airline (CX, RJ, etc) but my travel won't be a simple point to point and can become quite time consuming.

Bean counters won't simply accept BA fares and if I don't give OW alternatives will book me onto cheapest flight going.
