While many wait until the last minute to do their holiday shopping, United Mileage Plus members may want to get started early. The program has announced its mileage mall holiday shopping bonuses and we expect other programs to follow. United Mileage Plus members can earn 1,000 bonus miles when spending between $500 and $749 at 20 participating retailers at www.mileageplusmall.com through Dec. 21, 2009. Spend $750 to $999 to earn 1,500 bonus miles and 2,000 bonus miles when spending $1,000 or more. The bonus is in addition to the miles you normally earn for shopping online. Participating retailers include the Apple Store, REI, Macy’s, Kohl’s, Harry and David and Williams-Sonoma, plus 14 others. The maximum bonus you can earn is 2,000 miles and taxes and shipping are not included in eligible spending.
