Business Platinum, opened 1991, never requested a retention offer, $60K annual spend, used the airline/Dell credit. Offer 30K miles or $150 statement credit. The whole thing took way longer than I wanted with the rep pitching the Blue Business (actually a much better card for this company). Accepted. I feel it should have been higher based on spend and years, but it is too complicated to change. We are a "highly valued account!" so we have that going for us...
We have a second business that spends much more. I hope for a better offer in July.
