I am trying to obtain tail numbers for some flights to retrospectively complete my 5 month old's new passenger flight log book. Antonakis, FlightRadar24 and FlightAware sites are not giving me the answers since the flights took place too long ago.
This is the flight information that I have:
Flight No. Date Route AC 8036 29/10/2015 YYZ-PIT AC 8037 02/11/2015 PIT-YYZ AC 7508 05/12/2015 YTZ-YUL AC 7521 12/12/2015 YUL-YTZ
Any help or instructions on where to obtain info would be greatly appreciated.
Note that this question is not a duplicate. This question is not answered by the question, How to determine the aircraft tail number on a particular flight?, since these flights occured too long ago to be found through the methods discussed in the answers to that question.
