The share miles promotion is back. http://www.usairways.com/en-US/divi...?CAMPAIGNCODE=USShareLanding&c=USShareLanding If you transfer the maximum 50,000 Dividend Miles, your recipient gets 25,000 Dividend Miles extra on top. Transferring the 50k DM costs you $0.01 per mile, so the cost for transferring the 50k DM (incl. the 25k bonus) is $500 + $30 + 7.5% tax recovery charge, which is approx $569. As a comparison, you can buy 25k Dividend Miles for $687.50 + 7.5% tax recovery charge, approx $739.
