Are People Afraid to Fly on Halloween?

If So, Can You Save Money On Flights When Other People Are Scared?

I ran a quick analysis of US flight search data over the past two years on KAYAK sites, to find out the flight pricing trends on Halloween.

I looked at average selected airfare prices on Halloween vs. the overall average for the past two years. Prices were 5% less on Halloween. That's not a massive difference, but across such a large sample, it's statistically significant. Then I looked at other dates when people might be afraid to fly - Friday the 13th and September 11th. I found an even bigger difference here - average selected airfare prices were 12-14% lower than the average for the past two years.
