Where did you see this flight? Is this on AA metal? Cause the EXP desk claimed $850 was the lowest I could get through london.</font>
Go to aa.com, go to multi city and input NYC-MIA-MAD and return. For example I used outbound on May 18th and returning on May 26th. My search returned 10 results 8 of which were under $670 with the lowest being $624.

Lots of other routings and dates. But you have to fly M-Th.
