Yes, correct code. UA promotions are becomming very difficult to track and a pain to communicate with MP on thier system weaknesses.
I have the option of flying US or UA in the notheast (IAD to BOS and LGA are possibilities), and both US and UA are offering double-mileage promotions. I know that with US, the promotion mileage is posted within days. With UA it is months, and often a call to MP Customer Service, so I am reluctant to use the UA promotion while the US promotion is still in swing.
