Similar experience to moe8555 above.
Current open aviator no fee card account w/above 30k CL (downgraded from AF red card back in Feb '17). Applied for red card and went to pending review. Called number above, very cordial representative reviewed information, asked if I wanted to reallocate cl, confirmed bonus, and came back with approval. Newly approved and old account shows online. Very pleasant experience with Barclays.
