I had an evening flight that was cancelled an hour or so before boarding. I was at Sky Club T in ATL. I couldn't do anything on the app and was helped by an agent in the front of the club. Luckily, I was able to fly to my destination that night thanks to that gentleman. I gave him a JWD as a thanks.

Another time, I was coming from overseas flying out of LAX to JFK. For whatever the reason, I would not show up on the upgrade list but the front desk agent at the old LAX Sky Club was able to fix it and add me to the list. I had called the Delta line multiple times but no one could help. In the end, I didn't get the upgrade because there wasn't any seats available but I really appreciated her efforts. She got a JWD too.
