US Airways 100% Bonus On Purchased Miles Returns

Through December 20, 2013 (11:59PM PT, specifically), US Airways is offering up to a 100% bonus on the purchase of Dividend Miles. The bonuses are tiered, as follows:

Buy 10,000 – 19,000 Dividend Miles, get a 50% Bonus
Buy 20,000 – 29,000 Dividend Miles, get a 75% Bonus
Buy 30,000 – 50,000 Dividend Miles, get a 100% Bonus


So in order to get the 100% bonus you have to purchase at least 30,000 miles. US Airways ordinarily charges 3.5 cents per purchased mile, plus a 7.5% tax, for a total of ~3.76 cents per mile. So with a 100% bonus you’re paying ~1.88 cents per mile, which is fairly good. The deal gets less good if you just purchase enough miles for the 50% (~2.82 cents per mile) or 75% bonus (~2.35 cents per mile).

Earlier in the month US Airways ran a 100% bonus on shared miles, which was a much better deal since it was basically an opportunity to pick up miles for ~1.1 cents each. The “catch” is that you needed an existing mileage balance in order to share miles, so if you didn’t have miles in any US Airways account that wasn’t especially useful. We’ve seen two such 100% share miles promotions in the past several months, which is more than normal.

Anyway, 1.88 cents per mile isn’t a rate at which I’d speculatively buy miles, but if you have a specific use in mind it can still be a very good deal. US Airways charges just 90,000 miles for business class between the US and North Asia, and you can route via Europe with a stopover there. It’s anyone’s guess how much longer till they devalue their award chart, but spending under $1,900 to get enough miles for such a ticket is a bargain, assuming you can lock it in soon.

As a reminder, US Airways mileage purchases are processed by, so wouldn’t qualify as airfare spend for the purposes of your credit card (so if you purchase them you’re best off using a card that’s rewarding for “everyday” spend).


  1. Ben
    After 2 rounds of Share promos at 1.135c @50k per account =567$
    That is 1135$ per person x number of family and friends
    I am not sure this promo even deserves a post!
    Perhaps after we have booked the trips on US, we can think about it.

    AA sells miles for 2.1c usually so this may be a 10% discount at most.

  2. @ ffI — Agreed, accept:
    — American caps the number of miles you can purchase per year
    — I know a lot of people weren’t able to take advantage of the “share miles” promotion because they didn’t have any miles.

  3. Do you remember if the Share Miles Offer was also handled by I’ve not gotten the double miles from USAir Mastercard.

  4. When can you use USDM to book oneworld flights? Can you use the USDM chart values?

    I would like to do LAX-LHR-HKG on BA for 90K return. What about fuel surcharges?

  5. @ Mike S. — We don’t know when you’ll be able to redeem US Airways miles for travel on OneWorld. My guess is that miles will be transferrable to American eventually, so only bookable through their award chart and at their rates.

  6. sorry for the dumb question. i know US Air has the sweet spot of 90k biz from usa to north asia which can route and stop through europe. is there similar reward for opposite direction? i’m in tw right now and am looking to go back to states. would love to book a tw to europe to sfo back to tw trip in biz. or tw to sfo to europe to tw.

    is that feasible or not? thanks in advance!
