I have a business platinum card that I was planning to cancel in about a week (since that's the 30 day point from my annual fee hitting), but a great fare popped up today that made a lot of sense to book with the 35% rebate. Are there any data points on whether a flight booked while your business platinum was open will earn the rebate if the card is closed before the 30 day email? I'm probably just going to keep it open long enough to credit and then downgrade to a green since the difference in points would be pretty massive, but just figured I'd check
