US Airways and American Airlines have merged since the publication of this post so it is no longer valid.


Nine minutes ago, I received an email from US Airways saying that I was targeted to buy Dividend Miles with a 90% bonus from now through May 15. Check to see if you have the email.

Clicking the link to Buy Miles in the email, I was brought to a purchase screen where the bonus miles were automatically included. The normal US Air price for miles is $37.63 per 1,000 or 3.7625 cents per mile. I know it says $35 on the first screen, but when you click Continue a 7.5% excise tax will be added, bringing the total cents per miles to 3.7625

With the 90% bonus miles, I can buy a maximum of 50,000 miles and receive 45,000 bonus miles for 95,000 total miles at a price of $1881.25 after the 7.5% excise tax. 95,000 miles for $1881.25 works out to 1.98 cpm.

While my valuation series of US Airways miles won’t end until Wednesday, I can tell you that Dividend Miles are, in general, worth less than 1.98 cpm to most people. But I only like to think of the general value of miles when I’m contemplating the value of earning oodles of miles through a credit card sign up or the Grand Slam without having specific redemptions in mind.

So if you are going to buy 95,000 miles speculatively, with no particular use for them in mind, just because you think the price is good, you need to compare your general valuation of US Air miles to 1.98 cpm and see if this is a good deal. For me, since my personal valuation is below 1.98 cpm for Dividend Miles, this is a bad deal for me, and I will not be purchasing them speculatively.

If however, you have a very specific US Air award in mind, and will buy these miles for immediate use, you do not compare 1.98 cpm to your general valuation for US Air miles. You compare it to the value of the award. How do you do that?

This is one of the many uses of the Mile Value Calculator. Type in the value of your award, the taxes and fees to book it, the miles needed, and the miles foregone, and it will spit out a value of the award in cents per mile.

If that value is above 1.98 cents per mile, buy miles through this promotion to get to the amount you need. If it is below 1.98 cpm, according to your own valuations, you would be making a mistake buying miles at this price.

I’ll think over the next few days whether there is an award I would like to take this fall, and I’ll decide whether that award makes buying the miles a good deal. I’ll let you know whether I take advantage of this deal.

Who’s going to take advantage of this promotion?
