I’ve been getting a lot of emails asking whether Delta’s current promotion to buy miles with a 75% bonus between now and March 31, 2012, is a good deal.
The short answer is: no. Certainly not in comparison to past bonus offers.
As I wrote about in this post, Delta sells miles at a pricey 3.5 cents a piece plus a 7.5% tax. With this promotion, you could get up 105,000 for $2,257, or 2.2 cents each. Better than buying miles outright, but still very unimpressive – especially since Delta recently let you essentially buy miles for 1.1 cents each through their 100% transfer promotion. I personally would hold off unless you really need to top up your account.
