US Airways is running another round of double miles for mileage purchases. From now until July 31, 2010, Dividend Miles members can buy up to 50,000 bonus miles and earn a 100 percent bonus. For example, you can buy 13,000 miles for $384.31 (including tax) and receive a total of 26,000 bonus miles–enough for a roundtrip domestic coach ticket. While most domestic coach tickets can be purchased for less than $384.31, there are some routes that are more expensive. A much better value is if you purchase enough miles for a roundtrip business class ticket to Europe. For $1,478 (including tax) you can buy 50,000 miles and receive 100,000 miles, which is enough miles to fly in business class across the pond. Miles are $.0275 per mile plus tax.
