Go to airfleets.net or planespotters.net - you will be able to search by airline to find the registration numbers for each type of aircraft for each airline
Then go to flightradar24 (often abbreviated as FR24) and enter an aircraft registration - you can see a list of all flights an aircraft has done in the last 7 days for free (or more than a week if you pay !)
There are probably other ways to get the info you wanted but they may involve paying a pile of cash
