It seems that some people don't actually believe that this could just be a simple mistake. Knowing DL IT, I think that could be a legitimate possibility. If an IT bug goes through and allows E Fares (which were fares that previously did not earn MQMs) to be booked, than obviously the computer would show that the E fare wouldn't earn MQMs. It would hardly be an unannounced change if it was just a mistake (I'm not saying it wasn't intentional, I'm just saying that it simply could've been a mistake). Yes, DL has had a history of not announcing huge program-devaluing changes (and I think it's completely wrong and unethical) but, like I said, this could've just been a mistake. We shouldn't jump all over SMI and others who posted the internal DL announcement before we learn all the facts--I'm sure they'll leak out eventually.
