I booked my ticket on nwa.com and then realized I had an MCO from earlier in the year. I called NW reservations, hoping they could credit my credit card or something and was told the only way I could use the MCO is if I made the reservation on the phone. When I explained that if I did that, I wouldn't get any bonus miles for booking online, he said "Well that's just a choice you have to make". Is this true?
Thanks!
