US Airways more or less offers monthly promotions on the purchase or sharing of miles. In January they offered a 100% bonus on purchased miles targeted exclusively to those that purchased miles in 2012, in February they offered a targeted 100% bonus on purchased miles as well, in March they offered a “mystery” bonus of up to a 100% on purchased miles, in April they offered a 50% bonus on shared miles, and in May they offered a 100% bonus on purchased miles for everyone.
This month they’re basically offering a slightly better version of the April promotion. Through June 30 they’re offering a 50% bonus on the sharing of miles. Sharing miles (meaning transferring them from one account to another) ordinarily costs one cent per mile, plus a 7.5% tax, plus a $30 transaction fee.
Through this promotion they’re waiving that transaction fee and offering a 50% mileage bonus.
That means if you transfer 50,000 miles to someone else’s account you’ll really get 75,000 miles, and it will cost you $537.50, or 2.15 cents per “generated” mile.
So this is a good deal if you’re looking to top off an account, in my opinion, but isn’t a rate at which I’d proactively transfer miles unless you have a specific redemption in mind. During the standard 100% bonus on purchased miles they’re available for 1.88 cents each, so this is a bit more expensive.
The very best promotions that US Airways runs, however, are the 100% bonus on shared miles, like the one they ran last October. Through that promotion you’re basically paying just over a penny per mile, which is an amazing deal. Here’s to hoping that returns sometime soon…
