My seat: 7D, an aisle seat at the front of the Economy Cabin. There was a wall in front separating us from United First. It was as comfortable as it needs to be for such a short flight.
Fellow passengers: A mix of business and leisure travellers.
How full: Completely but the usual jostle for overhead locker space seemed to be quite orderly.
Entertainment: There are no seat-back, armrest or overhead TV screens on these flights, but you can watch TV shows and movies using the United app and free inflight Wi-Fi. I started to watch the movie I hadn't finished on my connecting flight from Auckland, but in the end just napped instead.
The service: Not much time for the cabin crew to do much, but the two female flight attendants were friendly and efficient. They handed out small bags of deliciously sweet wafer-thin, maple cookies and cups of water or orange juice.
The toilets: I held on.
Luggage: I had a through ticket from Auckland and had been travelling in Premium Plus, so had allowance for two checked bags.
The airport experience: I got through San Francisco quickly and easily, which was a nice surprise compared to my visit there last year which took more than 90 minutes in a queue to get through immigration alone. At LAX's Terminal 7, my suitcase arrived within 10 minutes and I was in my Uber about 10 minutes after that.
