Through 11:59PM CT on February 17, 2014, United is offering up to a 40% discount on the purchase of MileagePlus miles:
- If you purchase 15,000-39,000 miles you receive a 25% discount
- If you purchase 40,000-150,000 miles you receive a 40% discount
This sale comes just shortly after United massively devalued their award chart last week, so it’s even less valuable than it would otherwise be.
Miles ordinarily cost 3.5 cents each plus a 7.5% federal excise tax. If you max out this promotion you can purchase 150,000 MileagePlus miles for $3,386.25, which is ~2.26 cents per mile.
Mileage purchases can take up to 48 hours to post, and are processed directly by United, meaning they should qualify as airfare spend for the purposes of your credit card.
Anyway, it’s worth being aware of this promotion, but my guess is that it won’t be of interest to most.
