Rather than offering a straight 100% bonus on purchased Dividend Miles this month, US Airways is offering anywhere between a 25% and 100% bonus on the purchase of miles through March 31, 2013.
Just log into your Dividend Miles account here and you’ll get a prompt telling you which bonus you’re eligible for.
My account was only eligible for the 50% bonus.
While another account I manage was eligible for the 100% bonus.
US Airways miles ordinarily cost 3.5 cents per mile to buy, plus a 7.5% excise fee, for a total of ~3.76 cents per mile after tax.
That means the new all-in costs factoring in the bonuses are as follows:
With a 25% bonus: 3.29 cents per mile
With a 50% bonus: 2.82 cents per mile
With a 75% bonus: 2.35 cents per mile
With a 100% bonus: 1.88 cents per mile
Of those bonuses I’d say the only amount at which it can make sense to proactively purchase miles is with the 100% bonus. US Airways seems to offer a 100% bonus on purchased miles on an almost monthly basis, so if you’re not eligible for this promotion I’d suggest waiting till next month in hopes of a 100% promotion.
And if you can redeem your miles for a 90,000 mile business class award between the US and North Asia via Europe, I’d say it’s almost always an amazing deal to purchase US Airways miles.
