It did use to be 2 ROUND TRIPS or 4 ONE WAY SEGMENTS per day. If you go from NYP to HFD, you need to take 2 different train numbers, connecting in NHV. Do you only earn 2X one way? :huh:
Yes, they now cap the bonus at two segments per day, you can ride four segments but the second two to post don't get a bonus. If you ride more than 4 individual segments in one day the 5th and later segments to post doesn't earn you any points at all.
This started in around the Fall of 2012 if I'm recalling correctly, before all four segments could be doubled and infact tripled the few times they did a triple points week. I went up to New Haven to
'do' all the stations between New Haven and Hartford and earned 1,200 points on only $23 of Amtrak spend, (plus $23 of Metro-North tickets to get me up to New Haven)!
