EX-AMS, Delta metal
I called Delta 2 days prior to check-in to apply my GUC. Upon check-in, and also at KLM lounge, the staff could not see me on the wait list. They said it probably meant it was full.
At the gate I asked the staff there and they could see my GUC but currently flight was full. Anecdotal, but Delta app said 3 D1 available so I'm guessing that's not correct. 5 minutes after I asked gate they called my name and put me in 3C. 😎
