I'm sure it's already in here, but award ticket selection is deceiving. The low, medium and high calendar doesn't work. I was told there were only medium for outbound and return, but when clicking thru only got charged for low OW.
VERY disappointed that Deltas award availability seems to add 10-15K to every trip for this Gold. I used to book on nwa.com for significantly lower miles.
If I wasn't stuck in a hub, I would be so outta here.
