"MIA-LAX and LAX-LHR a few days later for a grand total of 20,000 miles and 3 quid tax!
The MIA-LAX flight should indeed be free of the dreaded surcharges. But LAX-LHR? I doubt it.
And MIA-LAX-LHR should cost a lot more than 20,000 Avios. LAX-LHR alone should cost 25,000 Avios in Y.
Typo in the OP? MIA-LAX-DEN, perhaps?
OP stated they used AA miles which do not incur fuel surcharges on AA metal and includes a free domestic connection.
