This is so variable on the routes you're flying. Example, CA beats the hell out of CX and JL on a lot of ex-HKG routes. Long haul between Asia-Africa then QR dumps a lot of cheap inventory on the market, same Asia-Europe both QR and MH still have cheap prices. Most of the time Japan to North America though its UA as the price leader. Going to Australia for me it's usually Skyteam leading the pack... but regardless of the prices, status is important to me and I don't fly 150-200k a year anymore to earn a level with lounge privileges on more than one alliance so I pay the *A rate and don't really even shop off-alliance.
