I flew out J-Class to YVR on Thursday and have to note that the crew seemed very happy, friendly and were attentive and open to conversation.
I was in the upper deck, so I can't comment on other cabins, but the two crew attending this cabin and the visiting CC and flight crew all seemed to be very jovial. I must admit that I was pleased to see this given some of the negative tales we've all read about.
As this was the first day after the strikes, the food services was down on usual, but that's the only criticism I have from my flight.
Let's hope my return to LHR is the same.
