US air fares

On average, have air fares in the U.S. gone up or down in the last twenty years? You'd want to know that trend not in dollar prices, but rather adjusted for inflation.

So here's the result, adjusted for the inflation that's taken place since then: I'm a little surprised to see that air fares have actually declined from 1995 til 2015.

"Although real airfares have been relatively flat for the last decade at around $375, the trend line in the chart above shows the downward trend in airfares over the last 20 years. Compared to the peak in 1999 when airfares topped $475 in the first quarter of that year and were above $450 in 8 quarters between 1998 and 2001, consumers today are saving close to $100 on every round-trip flight."
