BTS only has mainline domestic flights, which is extremely frustrating as I'm missing several regional flights and a couple of international. If you figure out where to find this stuff please update the thread.
I looked at the BTS website and as others commented it did not include some of the regional flights, including mine.
I found some information for international flights on this website..

Or this one too, which seems to link directly to the BTS database, but it only works for domestic flights
