I haven't seen the new one, but I did watch the old one.
Dealing with the public can be a pain in the ass. In today's horrible climate of flying, you can multiply that pain by 10 for the airline industry. Everybody is pissed off at waiting in long lines, including check in and TSA.
I can understand where Southwest agreed to show episodes where they didn't allow people on the aircraft due to being drunk or due to smelling too much, but I can't believe where they would show episodes where they bumped people from overbooked flights. Almost always these bumped people had a wedding or some other event to attend and there was no other flight leaving that day.
They also had one episode on lost baggage. I've been in the baggage claim place before, and it can't be a fun job. That person who writes the claims for lost luggage isn't responsible for it being lost, but he has to bear the full brunt of the passenger's anger.
Southwest still does it better than most airlines.
