Just for clarification, if I did a round trip between approved city pairs on Acela, First Class, it would be 1500 points, and under triple points, it would be 4500 total points, with only 1500 rail points. Do I have this right?

I would like it to be 4500 rail points, but as far as I understand it bonus points don't count towards rail points.

One more aside, are there other high point runs to make under triple points, or is first class acela the highest point run to make?

My home station is PHL, thanks!
