I am happy and surprised to report that I made two separate R/T business class bookings, ex-USA, on my wife's BA account using the Chase BA Visa, on December 28 and again on December 29. I was shocked to check her credit card account today and see two Chase "Redemption Credits" for $200 each dated January 9. So 11 and 12 days respectively, both auto-credited. The first ticket was for multiple pax including my wife the account holder (and thus cardholder). The second ticket was for me, again using Avios from her account.
