After you question I thought I would let you know how it went on my flight today. Today I had 7 GC in WT and WT +. Said hello to 5 , 2 were asleep straight after take off with eye shades on No idea how many in Club, but in First I noticed that there were 2 silver , 1 non card holder and the rest were all gold ( it was full). As you can see the numbers of gold card holders can soon add up on a flight. The reaction from the pax varied from “can I get them a better seat” ( which I did as we weren’t full in WT,so moved them both to a bulkhead aisle with no one next to them)., bemused, and irritated. I will carry on doing the welcome when I can, although it never feels a natural process.
