This is my first Amtrak trip. I am travelling from Pittsburgh, PA to New York City, NY inon the Pennsylvanian; and then from New York City, NY to Washington DC inon the Acela Express. Both the tickets are in Business Class.
I read somewhere that the ticket checker/collector will assign the seats for Coach Class tickets on the platform. I am not sure whether this is true in the case of Business Class seats. If not, then does Business Class have fixed seats/seat reservations; or is it just like Greyhound where you can sit in any seat?
If the Business Class have seat reservations, then how can I reserve/fix a seat on the train? While booking, I did not find a link to do that. Also, I have checked My Trips > Current Reservations page for a link, but there was no such link.
