it all counts as one segment and the flight is technically over 500 miles already so you do not get 500 for each take off

Like Jackal was saying previously. Personally I avoid those hop flights especially winter time but even in summer you can get low fog and other poor weather which causes a lot of delays, cancelations, and diversions. And if even the most minor pieces of equipment break or needs replaced it will take a whole day or two for a part to be brought in. I once was canceled in JNU for a torn windshield wiper blade because they had none in JNU
