Several times per year USAirways allows you to share miles with a friend and the friend gets double the miles you sent. This effectively allowed you to buy 50,000 miles for $567.50, or 1.135 cents per mile.
Unfortunately since the last promotion in April, USAirways has raised the cost to share 50,000 miles to $836.25, or 1.6725 cents per mile.
Additionally your friend no longer gets the full bonus. This time around you’ll split the bonus. In other words if you send 50,000 miles to your wife she’ll wind up with 75,000 miles and you’ll have 25,000 miles. Previously your wife would have the full 100,000 miles in her account.
Can it still make sense to buy miles at that price? If you’re using them to fly Cathay Pacific first class from JFK to Vancouver or on American first class from JFK to Los Angeles or S. Francisco or from Miami to Los Angeles for 50,000 miles round-trip, it may make sense. Though that rate goes up if you don’t book that by 07/31.
But this promotion is no longer the golden goose it once was.
