Yesterday's boarding process was interesting. Oh my how times have changed! They announced that due to the light load, boarding would be two zones. First class would board first, and then everyone else. Formerly a route with heavy business traffic where an upgrade to C+ would have been difficult. I was the only medallion on the flight. F cabin had 1 medallion upgrade (me), 2 paid pax, and 4 non revs. There were only two checked bags on the flight.
