The new alphabet soup is a bit hard to follow and parse through. I've compiled the details of all the fare buckets and made them look pretty. The information is now posted in the MilePoint wiki here: http://milepoint.com/forums/wiki/un...program-details/#mileage-plus-mileage-earning. That section of the wiki is written in the present tense even though there are a few of the changes that aren't going to be fully deployed for a few weeks yet. It is just easier this way. I hope you understand. Feel free to ask questions in this thread or to update it yourself if something changes and I haven't updated it yet.
