In case you missed yesterday’s news the American Express Business Platinum’s annual fee will be increased to $595 in February, they are also adding some additional benefits to try and make up for the $145 annual fee increase. Because of this I imagine many readers are interested in getting the card now before this increase. The current public bonus is 50,000 points after $10,000 in spend and an additional 25,000 points after an additional $10,000 in spend ($20,000 spend total). There are two better offers:
- Some people have been able to get 100,000 points after $10,000 in spend by using the call in method. This is very YMMV, but it has been working again recently.
- Affinityy shows the public bonus of up to 75,000 points. You get an additional $50 if you apply through the Affinnityy links.
- Referral links are offering the same as the public bonus. Self referrals work (or get a loved one to refer you) and the best offer currently is 20,000 when referring from the Business Gold Rewards card.
I don’t think there are any other ways to get other bonuses on this card currently but if there are then I’d love to hear them. Please do not share your referrals in the comments below.
