Why do airlines join IATA? What is the reason for any cartel? It exists to keep prices, and airlines' profits, artificially high?

International airfares are set by international agreement and regulated by the airline cartel, IATA. Most international airlines are closely related to, if not directly owned by, their national governments. Most governments in turn have an interest in protecting the profits of their national airline, and the IATA fares are therefore set artificially high.

As a condition of membership in IATA, airlines agree (voluntarily, remember) to sell tickets only at IATA-approved prices. IATA rules officially prohibit discounting, and in some countries these rules are actually enforced -- one reason some countries have no local ticket discounters (although tickets originating in those countries can often be bought in other countries, if you know where to look). Airlines like the cartel because it raises the prices paid by price-insensitive business travelers.

But it's not the whole story. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
