Through May 31, US Airways is offering a 75% bonus on miles transferred between accounts, up to 37,500 bonus miles and one transaction. The cost to transfer miles is one cent per mile, plus 7.5% tax, plus a $30 transaction fee. In other words, 37,500 miles would cost you $567.50, or 1.51 cents per mile (can someone double check my math)?
There’s also an offer for 50% off purchased miles through May 14 for those with the co-branded US Airways credit card.
All around, not as straightforward as the good old days of the 100% bonus on purchased miles, but still quite good.
