Update: The Starwood Preferred Guest business credit card is now the Marriott Bonvoy Business American Express card. See current offer and learn how to apply.

Yesterday I wrote about some new increased bonuses on the SPG Business card and four Delta Amex cards. I also mentioned that it’s probably worth waiting for the increased offers to show up through referral bonuses. And referrals are now showing with the better bonuses and also a different expiration date (for Delta cards).
