How to get Historical Data?

Hi I was going through flightinfoex api and getting information based on tailnumber.
In a similar way I would like to go for last one year data based on tail number.
Could you please guide me how to proceed in this case.

Historical data older than 2 weeks needs to be obtained by either clicking the “Purchase flight history” button on the website tracking page for that flight, or by ordering a custom report from our data consulting team.
