As you have 4 sectors over 2K miles, you should get 4*180 tier points +40 for the internal hop, if it's in business. In total, 760 points, well over the 600 needed for Silver. You should get 2* miles for 1st, also a 25% bonus kicker when you hit Silver, though you'll only hit SIlver on your last flight. It's a shame you can't put a few more sectors in to boost the miles/points.
