I am a citi member so I assume I can use the A074800, or if not I am a costco member and can use A108379. But I'm wondering if I can use either the citi or costco AWD with a 2 free upgrade coupon out of my entertainment book, or use the citi AWD with the Costco coupon code? The entertainment book coupon has an AWD with the coupon code but its not very good.
Thoughts??
