I stared at my recent UA mileage summary and finally figured out how they are posting miles under the new system. Not rocket science, but not so obvious either. They have it broken down into two pieces, the "spend" for each leg X 5 to calculate the "Base miles", and then the same "spend" x whatever else you have coming to you, depending on your status. Since I am currently 1K, that means that the "spend" is multiplied by 11 - 5 = 6 to derive the "Bonus miles". Of course, if you are only interested in how many miles you will get for your full itinerary, without the segment-by-segment breakdown, you can just look the item labeled "Airfare" on the receipt. Recently purchased itineraries also have a table further down called "MileagePlus Accrual Details" with all the nitty gritty, but older itineraries don't display this detail.
