If I upgrade from BR Gold to BR Platinum for the 50K bonus will this mean that if I ever see a 100K offer for BR Platinum that I won't be able to apply for it? I know that Amex has a once bonus per card in a lifetime, but not sure how this would be handled since its a bonus for an upgrade. I would hate to accept 50K and then find out that I can't apply for 100K at a later date because I already accepted a card bonus.

You are not eligible if you have previously held the card. It does not matter if you did, or did not, earn a bonus. That said, it isn't clear if American Express' system accurately tracks changes between Green, Gold and Platinum for bonus purposes. I can only say that accepting this offer might disqualify you from a future Business Platinum offer. (Targeted Business Platinum offers as high as 250,000 points have been reported.)

Thanks mia, if that is the case I'm likely going to turn down the offer. I'd rather wait until at least a 100K offer comes along.

Is Business Rewards Platinum the same as Business Platinum?

To my knowledge there is no card named Business Rewards Platinum.

My bad. I think she said Amex Platinum... Honestly, I received the call this morning about 2 minutes before I had a work meeting, so I politely asked them to call back. I'll ask for more details such as how much my annual fee will be when it hits next month. But, it sounds like I should wait for a better offer (then 50K for $10,000 spend and no annual fee waived). Is that the consensus here? I was planning to cancel/downgrade before the BRG fee of $175 hit.
