I am amazed by the myth that airlines are charging too much for flying. Some basic research would quickly reveal the reality of the situation.
According to a 2011 article in Businessweek, the average price a passenger paid per mile in 1974, adjusted for inflation, was 33.3 cents. For the first half of 2010, that average was down to 13 cents. The cheapest New York-to-Los Angeles ticket allowed under regulation in 1974 was $1,442 in inflation-adjusted dollars. That fare can now be found for far less, including bag fees.
Meanwhile, a barrel of oil in 1974 cost about $40 in inflation-adjusted dollars; now, it's more than $90. Most products and services are way more expensive now than they were 40 years ago, and yet flying is significantly cheaper.
