Right, including the 1.5 EQM and EQS "extra" credit, which helps you get to Elite faster.
Watch your Mileage Plus statement, though, since sometimes the computer doesn't recognize the class of fare bonus (they show it as "K" class). In such cases, you have to send a copy of the ticket (or the receipt) showing the "Y" or "B" class to the Mileage Plus Service Center in order to get the 1.5 instead of 1.0 credit.
