Last time I went to Diannan, I was accompanied by the sisters Nana and Xinyu; to Yanjing, Fang Minhui was with me.
This time going to Shanghai, it was just me, not even an assistant.
But the more it was like this, the more there was a sense of unknown anticipation.
There's a bit of a difference between business class and first class; the first class I took the previous two times had private compartments, arranged in a 1-1-1 configuration, providing a fairly secluded personal space, with adjustable seating angles and leg support.
While business class on this trip was arranged in a 2-2-2 configuration, with other passengers just across the aisle, and the comfort of the seats differed from that of first class.
I heard from Ji Ya that domestic flights are mainly short to medium haul, plus most of them are on small aircraft, so offering first class isn't cost-effective.
For example, this Airbus A320 didn't have a first-class cabin.
