Last August an offer came out promising up to 90,000 miles for the Virgin Atlantic co-brand credit card. It returned at the beginning of October. Links come and go for the offer.

Now, these are Virgin Atlantic miles which aren’t the most valuable. And the offer requires a whole bunch of spend. So it’s not the greatest card offer out there. In fact, I view the card as 75,000 miles for $12,000 spend and wouldn’t take it all the way to capture the full 90,000 offer on the table.

But it’s from an issuer without too many co-brand cards (my only recent Bank of America card is an Alaska Visa), and it’s potentially a lot of miles.

The good news is after the most recent link I had died a couple of months ago the offer is back.

This card used to come as an American Express (one of those oddball American Express cards not issued by American Express). Now it’s a MasterCard.

Perhaps the best thing about the card is that there’s an explicit offer for expats who lack a US credit history.

It’s advertised as a signup bonus of up to 90,000 miles but I wouldn’t think about it that way. There are several pieces to the bonus, and you should probably take less than the full miles. And you should know that Virgin Atlantic miles are among the least valuable.

Sign up. Put $12,000 on the card. And you get 70,000 miles. Add authorized users and it’s 75,000 miles.

Now, if you’re going to do $12,000 in spend, you might as well spend $3000 more for an extra 7500 but that does require keeping the card through its anniversary.

There are some unique benefits of MasterCard and this card is being issued as a World Elite MasterCard. Those have much better travel benefits than simple World MasterCards do.

Virgin miles are fairly easy to acquire. Points transfer into Virgin from both American Express Membership Rewards and from Chase Ultimate Rewards.

I’m not a fan of Virgin Atlantic miles, although I have a ton. This offer is strong enough that it has tempted me many times. But I’ve never redeeemed the points. That’s why I put together a list of the great ways to redeem Virgin Atlantic’s miles.

Of course where paid travel would entail a fuel surcharge, Virgin adds that to the cost of an award ticket. They’ve reduced fuel surcharges on economy awards but those aren’t the awards I’m looking for. (Better off in most cases using Delta miles for the same awards on Virgin flights.)

What’s more, departures in a premium cabin originating in the U.K. entail a substantial tax — on top of the surcharges. So Virgin award tickets often aren’t cheap.
