I made my reservation over the phone in May and within the week went to the station and paid in person and got the ticket. I received an email overnight from amtrak saying "eTicket for your Upcoming Trip". In the email it states "Purchased 5/25/2013" & "Modified 6/5/2013". I have personally modified nothing. I have looked over the email and my corresponding original tickets and see absolutely no difference. Is this anything to be concerned about? The price is exactly the same as well. Thanks for any help!
