The point is not about what routes Southwest and Pan Am competed on, or whether in the 1970s 12 sectors was inhumane, but that there is still a company in the aviation industry which treats its staff as important people, and its passengers too I believe (although I have never flown with them as a pax), and manages to be a success at the same time.
In Europe and the USA at the moment, all the other companies appear to be going in the opposite direction, and which side is correct remains to be seen. Personally I like the Southwest option.
