Here's another e-ticketing related question:
In two weeks, I am ticketed from NYP-ESX. I may get on at NYP, but there's a chance that I will board at STM (next stop, about 50 min later). If I do choose to board at STM, I assume I need to change the ticket with Amtrak, correct?
However, will changing the ticket increase the price? I bucket has undoubtably increased since I bought the ticket. Would I really have to pay Amtrak more for a shorter journey?
Also, I used a promotion code that requires a minimum of a three day advance purchase. Would this cause me any problems?
Or is there some mechanism in this new system that will allow Amtrak to let me board down-line while preserving the fare I paid?
