In the 2009 Mileathon my wife and I did multiple Key and Chase debit cards. Some did not credit. I had emailed OnePass twice during the Mileathoon period asking if I'll get multiple credit and got one response saying yes and one no. Afterwards, I emiled asking for credit and was told that the only activities that can be repeated say so and the debit cards do not say so. [BTW OnePass has some of the worst CSA of the major airlines.] Note you'll only get credit this time around with the prffered ($65) debit card.
