Delta is offering double miles on mileage purchases through August 30th for first-time buyers. So if you buy 10,000 miles, you get 20,000. That brings down the effective cost of purchasing miles from 3 cents apiece to 1.5 cents. I haven’t ever purchased Delta miles before, so I’m eligible for the bonus, but 1.5 cents is still more cash than I’d part with to acquire Skymiles.
Still, if you need to top off an account for an award this could be just the ticket.
Presumably folks that have purchased miles in the past will be receiving a promo to buy miles again in the near future, since the offer says
Already a Buy Miles customer? Then make sure that you have added an email address in your account profile so you don’t miss out on your upcoming exclusive promotion.
