Where can fuel consumption data by aircraft type and route be found? I am interested in building a data analytics platform for fuel consumption by aircraft type and route. I imagine this kind of information is readily available to airlines thanks to ACARS data. I need the data to build CO2 emissions models.

Are they any freely-available datasets or do I need to get this information from an airline directly?

Thanks!
I am providing an answer to my own question. However, hopefully, someone will be able to expand further on this.


For US Airlines, the bureau of transportation statistics is a reliable source. And the data is free!
