Aircraft registration for past flights
I am updating my flightmemory.com with all the flights I have taken a couple of years ago. I have kept all the boarding passes, therefore I know the basic flight information and I can remember the aircraft in most cases, but of course I do not know or failed back then in getting the aircraft registration.
Has anyone an idea of how I can find out that information.
I tried a google search and on airliners.net there was a link to the Bureau of Transportation Statistics but once there it says that the link is broken.
Any information would be greatly appreciated.
Thank you
