American has just announced two promotions for the purchase of AAdvantage miles.
The first promotion runs through August 30 and offers tiered discounts on the purchase of AAdvantage miles, up to 25%. The chart for that looks as follows:
The other promotion runs through August 15 and offers 2,000 bonus AAdvantage miles if you purchase 20,000 or more miles.
So if you max out this promotion you’d be purchasing 62,000 AAdvantage miles for $1,365.31, which is ~2.2 cents per mile.
As usual, you can purchase a maximum of 60,000 miles per account per calendar year, and points purchases are processed through points.com, meaning this doesn’t qualify as airline spend for the purposes of credit card bonuses.
This isn’t a rate at which I’d speculatively purchase miles, but if you have a specific use in mind this promotion can certainly be worthwhile. For example, 67,500 miles gets you a one-way ticket in Cathay Pacific first class between the US and Asia, so if you have just a few thousand miles in your account you’d have enough for such a ticket.
If you’re just speculatively purchasing miles (which I don’t typically recommend) the US Airways sale for 1.88 cents per mile is probably a better value, or otherwise the Lifemiles sale for 1.5 cents per mile might be worth considering.
