Trenitalia tickets for two people on one phone?

You can scan both of them from one phone, but that can be awkward going through some turnstiles. It’s better to have them on each train passenger’s phone.

The QR code is what matters for getting through the turnstile or passing muster with the
conductor on the train, so you can either forward the email the tickets came in, or,
print a pdf of that mail and forward that file for your travel companion. It will be
obvious if you both try to use the same QR code.

It isn't that complicated. Download the Trenitalia app, or go to their website, and create and account. Create a personal profile for each person traveling within your account. Then search for the trip you wish to take - add both profiles to the trip - you will then get appropriate tickets/QR codes. It makes booking travel for a group easy - for three or more, it will automatically add available group discounts to calculate the fare.

Has there been a major change in the last year at Italian train stations? I'm afraid the OP could be mistakenly left with the idea that there are turnstiles at the stations before boarding. I've taken trains in Italy probably fifty times over the years, including two years ago, and 95% of the time, there are no turnstiles or ticket checking of any kind before you board the train. Tickets were checked by a conductor; occasionally when boarding; but usually only during the train ride. And I always had the info for both my and my wife's ticket, which I showed the conductor, no problem. There are entrance gates at a very few large stations (Rome, Milan) to access the tracks, but we never had to actually scan anything; just show our ticket info when passing. Unless something has changed recently, my answer to the OP would have been 'yes, no problem to keep both tickets on one phone; it is very common and not a problem.'

”There are entrance gates at a very few large stations (Rome, Milan) to access the tracks, but we never had to actually scan anything; just show our ticket info when passing.”

Now those entrance gates have scanning machines, similar to the metro, where you need to scan your QR code to have it open. I saw a couple trying to pass a phone over the top of the opening, so the second person could scan the same phone.

In Milan in October, we could not get to the tracks without first scanning our tix at the turnstile gateways you needed to pass through to get from Milano Centrale’s building to the train tracks.

And, as Jean wrote, the entrance lines became a bottleneck when one travel group’s QR codes were all on one phone.

I have travelled like that. It is not really a huge issue. At a gate I scanned first my wife's ticket, and she went through, and then I went. We did the same in the Netherlands.

But with Trenitalia you can always give everyone the PNR of their ticket, and then they can load it in the app themselves. You can even do that with tickets you bought elsewhere, eg. from SBB or DB.

Now I hope that the chaos at the gates has Trenitalia reconsider wether it really was a good idea to have those in the first place. (Anything that makes your passengers queue should be avoided, reallly...)

Speaking as someone whose phone just broke, it is helpful for each to have a pic of the ticket on their phone regardless if you do the hand off or not. I just take a screen shot of the ticket and text it to my partner so we both have the tickets. Many times we have needed to do the handoff and generally it has not been a problem even with crowds.

My husband never has the tickets. I stand slightly to the side, scan his ticket and then scan my own once he’s cleared the space. Easy-peasy. Don’t worry about the people behind you. They’ve all had to do his one time or another and know what’s going on.

Thank you, everyone, for all your helpful information. I enjoyed reading about your experiences.
(Elizabeth, if we had done what you did, we could have avoided any problems.) I feel more prepared now.

The first time we didn’t print paper tickets, I had a learning curve, too, going through before my husband, after fumbling to find the e-tickets in a lost email. Since it was Paris, the complaints behind me from the younger passengers who were born with phones in their hands were vocal. Lesson learned. Now the tickets are always in my Apple Wallet and Monsieur passes through before Madame.

Yes, you can keep both tickets on your phone with the Trenitalia app, but it’s usually easier if each person has their own ticket on their own device to avoid sharing hassles when boarding or exiting.
