I know that Amtrak fares are revenue managed, with the idea being the further in advance you book the cheaper the fare will be.
However I am looking at dates over 8 months time and the variation is startling. Yesterday, the fare was $122 with a roomette at $219. Today, the same route is $160 with a roomette at $302.
I used to work in the travel business so know about fare buckets etc. but was wondering if my own repeated searches is affecting the price as I haven't seen such changes so far in advance.
