Ah I see. You know, if the team have hard time finding information regarding the demand for Q1 of 2020. It's okay to use data from 2018 or 2019, just a suggestion.
There's some info here, hope this helps a little:

That might be helpful but for the most part I have all the data I need. Now it's mostly a matter of formatting and uploading it in the game.
Both airports should have similar demand, because Guarulhos is indeed the busiest airport in the country, because it handles almost as much domestic traffic as Congonhas as well as 100% of São Paulo's international traffic. Congonhas, on the other hand, is for domestic traffic only. If Guarulhos was 1333 before the dip, Congonhas should be around 1200 to 1400 too
I'm using real-world values and in cases of multiple airports for a city it just depends on what gets more use. Some airlines that use CGH as a hub do not use GRU as a hub and vice-versa. Since CGH is exclusively a domestic airport some routes that CGH serves are not served by GRU, reflecting real world conditions.
