Tahsir forwarded to me the following offer for the Business Gold Rewards Card that was emailed to his friend:

75k bonus Membership Rewards
after spending $5k in the first three months
all the other features of the card's standard offers

Everyone should check their emails for a similar email from American Express with the subject: "Your pre-approved offer ends 10/6. Earn 75,000 Pts"

If you don't have one, it's possible that the offer will be public tomorrow.

How good is the offer? Who can get in on it?

This is an incredible offer.

As many of you may know, I am a college student by day and the amusing, yet mystical, Bengali Miles Guru by night. After traveling almost 100,000 miles since January, I knew that my upcoming spring break trip would have to be amazing.

American Express Membership Rewards are valuable because of their ability to be transferred to dozens of partners. But they have a glaring weakness: they don't have a top-tier Star Alliance transfer partner--US Airways or United.
