CAA January - October figures 2021 for Teesside.
Terminal Passengers 59,394
Transit Passengers 6,369
Rolling Passenger Numbers for the year: 61,338
So going off the monthly figures they are collected by public services and charter flights. So that leaves 1,944 other passengers, I would presume that this figure includes business jets etc. This figure would include the Prime Minister Boris Johnson's multiple appearences this year at the airport and royalty.
