Where to find 2cpp deals?

Hi, I have read people getting 4cpp for business flights. Where can I find these deals? Are these deal rare? So far all the flight I am trying to book comes back at 0.74cpp. This is worse than cashback for 0.77cpp.

it’s not a deal. when redeeming for a business flight it can be around the equivalent of 4cpp. but you don’t receive any cashback like some cards offer for less than 1cpl
