Online Travel Booking and Bidding Agencies - AA discount business ex LHR

Looking for best online source for AA business class fares. They are consistently much higher than others from London and if I cant get my costs down company will pull approvals on AA fares. Anyone know of someplace would be obliged.
Primary destination EZE.

Welcome to FT!
I assume you are looking for a booking agent other than AA's. If so, I'll let this thread stay here. If not, let me know. I'll move it to AA's forum.

Hi thanksalot.
Yes, any booking source really will help. Agent/online.
I really want to maintain Exec Plat status but it is becoming
harder to justify AAs pricing against others, even BA.
