About two weeks ago, Northwest posted bonus miles for this Mom and Dad promotion, where you suppose to get 500 bonus miles for every $50 dollar spend, but they posted as "500 miles for each purchase of $50 or more", so my three purchases only got me 1500 bonus miles.
I then send them a email and I knew many other people sent too. NWA realized they screwed and promised to post everything else by today, which they did. Everything is there. Happy to get extra 60K NW miles, enough for 2 business class ticket anywhere within Asia
