The other day I booked a round trip where there were U seats outbound (SEA - MSP) only; however, out of habit, I added myself to the upgrade list first for the whole itinerary. I had to call AS to have myself removed from the outbound waitlist, and then apply a Gold Code myself. In this case, I found it a great use of a code, because there were no G/T fares left, as well as no aisle seats on the entire plane (first seating was wide open). I've used a second code for the 5PM ATL - SEA flight in May, where I had to search a few weeks of dates to find that black U needle in the haystack. Still not sure what I'll use the other two codes on.
