In addition to the American Airlines AAdvantage promo that we posted about earlier, there is also a similar promo for US Airways miles.
Terms are pretty much the same for this promo. For every 20,000 Starpoints you transfer, you’ll end up with 30,000 US Airways miles. Offer is good through July 30, 2014.
You can read about the USAirways award chart and benefits over here.
Unlike Starpoint transfers to AAdavantage miles, where the name must match for the transfer to go through, USAirways is (as of now) more lenient and will allow transfers even from accounts where the names do not match.
Also If you have a US Airways Premier World MasterCard, you’ll get a 5,000 mile discount on US Airways award tickets.
