I have the following itineraries:
LHR-SJU-LAX and LAX-SJU-LHR. Transatlantic sectors on BA in J, domestic on AA in F. Booked at 2 separate 50k SAAver awards.

Availability came up on LHR-SAN in both directions in F which suited me a lot better so that has now been booked.

I now need to cancel the first award and get the miles redeposited to my AA account.

Please can you advise is it better to do this
a) online in the "My reservations" part of aa.com
b) by calling them

I am aware that I need to pay to redeposit the 100k miles - do they take this from the taxes already paid or do I need to call to pay separately?

Thanks in advance
