This includes routes for 13 airlines that fly out of Boston. They are: American (AA), American Eagle (AE), Alaska, Allegiant, Delta (DA), Delta Connect (DC), Frontier (FA), JetBlue (JB), Spirit, Southwest (SW), Tradewind, United (UA) and United Express (UE).

There are 136 files but several of them are the same route, just separated by carrier to assist with livery selection.

I haven't included seasonal flights or flights beyond the contiguous United States. I'll do those in a separate upload.

To load your selected route, click "load/save" at the bottom of the World Map and navigate to the relevant folder. Note that the spawn location is set to the runway by default, so select your gate in the dropdown menu if you're looking to start cold and dark.
