The business class seats did eventually disappear yesterday, late in the day, so I assume someone was able to book them.

but this is OK; flying with BA we can spend a couple of extra days in Italy instead of traveling to Frankfurt over those two days. It does cost more though, due to BA’s crazy high fees for miles tix in business class.

We actually normally fly BA using their mileage plan (Avios), but when we run out of those we use our Alaska miles. We have had two good experiences with Condor recently, so it seemed worth a try even though we were starting from Italy.
