The reservation vacillates between showing on the app and not showing. Sometimes I can get the seat map to show with the old seats, but any change (to put 2 of us together) does not go through. Sometimes only a blank seat map comes up. The Amtrak.com website shows the "upcoming trip" but "We are unable to retrieve your reservation at this time." to see details.
The phone line read out my reservation, with what seemed like two different seat assignments (it's a one-way trip).
Then to add insult to injury, Verizon marked the Amtrak call-back caller ID as junk and sent it straight to voicemail.
So I'm waiting on hold.
