Who’s miles to burn, that is the question.

Looking to book award flights on American. We have both BA & AA miles. For AA it’s off-peak, so 30,000 AAdvantage miles, however BA doesn’t have off-peak so it’s 35,000 BA miles. Taxes are the same.

I generally value AAdvantage miles more due to the lack of a fuel surcharge, but as we all know that could change tomorrow.

Here’s the question for FT’ers

Do I:
(a) Burn the BA miles while I can w/o a fuel surcharge
(c) Burn the AA miles while it's an reduced mileage award

We have about an even number of miles with both carriers.
