Little in there that I can agree with. I've not flown in America or with a US carrier for some time. As for Europe, off peak to Spain cost me around £110 return in the late 80's, pretty much the same today. The staff on any airline seem more friendly than the jobs for life BA CC that just held economy passengers in disregard. Booking a ticket is easier and much more transparent.
And if he really wants to talk technology, lets look at aircraft reliability and punctuality in the 80's and today - its a different world. And lets not forget the technology in the ATC and navigation world that allows far more aircraft to fly in the same space in safety.
