If you would like to add to your United MileagePlus account to redeem for an award, or are looking for a quick way to keep your miles active, you might be interested in this latest offer from the program. United MileagePlus members can receive up to 60 percent bonus miles when buying miles by Sept. 5, 2013.
The bonus percentage will be determined by the total number of people who purchase miles by Sept. 5. The current transaction count is over 1,000, which means everyone who has purchased miles will receive at least a 50 percent bonus.
The percentage could still go up to 55 percent if there are between 1,251 and 1,500 purchasers and 60 percent if there are over 1,500 purchasers.
Unfortunately, you must purchase a minimum of 5,000 miles to participate, which will cost you $188.13. If you receive the maximum bonus of 60 percent, you'll receive a total of 8,000 miles, but there's no guarantee that the deal will attract over 1,500 purchasers.
