A nice surprise was that the LUX flight departed from gate 9 which is right next to the Cathay lounge, so I didn't need to leave the lounge early for the marathon walk to the other end of T3 like I did for the SOF flight.
In flight, lunch was the prawns. There were very good. I chose them again later in the trip. The deserts are already starting to get a bit repetitive. I am sure I have seen this cherry trifle before...
