I need to buy a round trip ticket from NY Penn to Baltimore Penn, but I since I don't have my own credit card I would have to use my Mom's. Am I allowed to do this? Will I be need to show the credit card to an Amtrak employee before boarding the train? I'll be traveling alone, so I won't be able to present the card, or have my Mom vouch that it's her card. I've never used Amtrak before so I have no idea how this works.
If I can't use some one elses credit card, can I go to NY Penn a few weeks before the trip and pay in cash at the station for my tickets?
