I also tried OBB where it says “Ticket not available” when I chose seat only option. But it shows $50 when I choose ticket option

any help? @rvdborgt 

ItaliaRail is just a guy who lives somewhere close to BOS/Mass and makes some pocketmoney by arranging this in his own/but for USA foreign lingo.

Without further details (how many times do we still have to tell that? WHEN, What train/connection?) IMpossible to answer. Most likely-certainly for USA; youre (again ) WAY too early. OR an overtheborder train/ride. Remember: eye-opener: untill very recently REServ for trains in EUR only opened 2 month advance-

.

And NO-you do not have to have eternal fears about trains being full so long ahead.

Thanks, I have added my train details in the post “Going from rome to florence on 27 aug 18:10 train”

Personally, it’s not early for me as june-august is peak time so I’m just trying to get organized because yes you’re right, I have fears about the trains being full in peak season and since I’ve only JUST recently learned that seats for pass holders are limited. 

I’m gathering that it’s pretty relaxed in Italy and I will just have to go against what I’m used to, and book tickets when I’m there?

You have to use via ÖBB for trains with compulsory reservation the one way ticket option and then at 1x adult put the discount Interrail/Eurail Globalpass. 

only seat reservation works only for trains with optional reservation (like Austria, Germany, ...)

What @seewulf says. Please follow these instructions and you will see prices.

yes I managed to do it this way! thanks @seewulf @Angelo
