When flight tickets get cheaper in advance - v2

In When flight tickets get cheaper in advance - v1, I wrote a Google App Script with Google Spreadsheets to track when flight tickets get cheaper in advance. In that script I weekly tracked the minimum return-ticket price from Sydney to Colombo for a fixed departure date (07th of April 2014). In this post, I improved the script and automatically calculated minimum return-ticket price from Sydney to Colombo daily for last 8 months without restricting to a fixed departure date. These details say, for a given date, ticket prices get minimum in advance of 110 days in average (given that you have no preferred departure date).
Here you can find the spreadsheet which contains up-to-date data-set and followings are the charts extracted from the data-set.

When flight tickets get cheaper in advance - v1

I wrote a small Google App Script with Google Spreadsheets to track when flight tickets get cheaper in advance. I weekly tracked the minimum return-ticket price from Sydney to Colombo for a fixed departure date (07th of April 2014). The answer was, ticket prices get minimum in advance of 5 months in average. Due to the disappearance of Malaysian airliner, MH370, I noticed a sudden fall of Malaysian air-line ticket prices after 8th of March 2014. So I added two charts. 1st one doesn't includes deviations related to MH370. 2nd chart includes the relevant deviations.
