LHR-DEN (3 class service) July last year, following op-up from WTP to CW the day before travel (no Avios seats going) and then being put in 1E/F on a 4-class 777 while in GC!
Chatting with the CSM about our trip to visit family for my wife's birthday just before landing, he disappeared and then came back with a bottle of Taittinger, saying [PREMIUM] Happy 30th Birthday Mrs gustavmahler. Enjoy this with your family while you're in Denver [/PREMIUM].
Got fantastic service on the whole flight.
