I noticed this evening that US is running a double miles promotion, for tickets in economy or Envoy booked with a Mastercard to Amsterdam, Brussels, Manchester, Dublin, Madrid, or Tel Aviv. For US Airways Mastercard holders, the double miles count toward preferred status. Purchase between March 15 and April 30, 2010, travel between March 15 and May 31, 2010.
