Yesterday reader Mike brought an ancestry.com offer to my attention.

Mike writes,

An easy 5k US miles for $24.95.

Ancestry.com has a 14-day free trial, and then you select your plan — each of which comes with US Airways bonus miles. The 12-month offer at $24.95 per month earns 5000 US Airways miles.

Presumably Mike is thinking, “sign up for this offer, get the 5000 miles, then cancel and pay only one month’s charges.”

Good plan and that may work. I’m not 100% sure, though. You can cancel an ancestry.com subscription at any time, so you should be able to cancel as soon as your miles post. And I imagine they’ll post within your first paid month.

But it also appears that they bill the full 12 months in one payment up front, rather than billing $24.95 per month as it would appear at first blush. And while they say you can cancel at any time, they also say no refunds for unused portions of your subscription.  So the worry here would be that 5000 miles costs $300, not $25!

Flyertalk discussion is here.

If anyone tries this and gets 5000 miles for $25, let me know. But in the meantime, this may just be a good offer if you actually were going to sign up for ancestry.com anyway.
