Changing seat reservation on Trenitalia

You can use the link below with the PNR code or use the Retrieval/Recovery code. This is from the 'Manage your tickets' area of the website. There may be limitations on what edits you can do, depending on type of ticket.

I tried that. No option for changing seats just the ticket itself.

I think I'll have to wait until I get to the station.

I never figured out how to do it online Frank. They do not run it like an airline res system.
