It's also quicker to fly there rather than transfer!
For example, this morning I was in Madrid and wanted to get to New York. I flew to LPPT, and there weren't any direct flights to New York. So I decided to fly to New York via KATL, and it ended up that I got there in 12 hours as opposed to 24, cutting the time in half!
That aside, thanks for ProPilot. It's an awesome addition to Flight Simming.
