And therein lies the problem.
In the mid-70s, a return airfare to Europe was around $2000: now it's ....... $2000! Of course, $2000 bought a hell of a lot more 40 years ago.
Today, cheaper is better and that's the whole ballgame. So the last airline left standing has won the game .... just before it goes broke. It's a ridulous situation and a ridiculous industry. Time for governments, bankers and IATA to get involved, or we will just see the accident rates of the 50s return as more and more airlines risk going to the wall unless they cut their margins (including safety and training) to the absolute limit.
