This includes routes for 35 airlines that fly out of Boston. They are (with filename prefix): Aer Lingus (AL), Air Canada Express (ACE), Air France (AF), Alitalia, American (AA), Azores, British (BA), Cabo Verde (CV), Cathay Pacific (CP), Copa (CA), Delta (DA), Eastern (EA), El Al, Emirates (EM), Frontier, Hainan, Hawaiian (HA), Iberia (IA), Icelandair, Japan (JA), JetBlue (JB), KLM, Korean (KA), LATAM Brasil (LA), Level, Lufthansa (LH), Porter (PA), Qatar (QA), Scandinavian (SA), Spirit, Swiss, TAP Air Portugal (AP), Turkish (TA), Virgin (VA) and WestJet (WJ).

In this instance, "international" means outside the contiguous United States.

A couple of the flights wouldn't be direct in real life, due to the range, but all of the flights here are non-stop. All (except one to Canada, I believe) are high-altitude IFR.

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.
