Hello Dazmond. Don't mind asking your questions! The SBB site is the one I referred to (so you're trying at the right website), but the procedure I described is suitable for ordering international train tickets and seat reservations. That's why I pointed this out for booking your trip from Rome to Interlaken. You can pick a 'GA' option (equal to the Swiss pass discounts) for international trips, so that the booking system can charge you for the foreign (in your case, the Italian) leg of the journey, but not for the Swiss leg.
For trips within Switzerland for which seat reservation isn't required, or even is impossible, it makes sense that you can't choose the GA option. Making the trip with a GA/Swiss Pass means, after all, that the entire trip is for free, and apart from that you can't even make seat reservations - so nothing would be left to order. Seat reservation isn't possible for the trip from Domodossola to Interlaken, and the entire trip is for free with your Swiss Pass, so there's no need (and no possibility) to order a seat reservation for this trip in advance.
The SBB system only offers either regular full prices or half fare prices. As the Swiss Pass offers a different discount (25% instead of 50%) for the Jungfraujoch trip, you can't pick the right fare when ordering your ticket in advance. If you wish, you can order your seat reservation for the Jungfraujoch trip through the Jungfrau Railways website
. You may also be able to purchase your ticket through the webshop there, but currently there's error on the page, so I can't check. It may be wise though to reconsider purchasing this ticket in advance. It's an expensive trip, and if weather is bad at the day for which you reserved seats and ordered your tickets, it may be a waste of your money. The tickets can easily be bought at a railway station (such as Interlaken or Grindelwald) before boarding the train, with the appropiate Swiss Pass discounts. A local purchase would allow you to make sure that weather is fine before leaving.
As far as I know, the SBB website doesn't allow you to make seat reservations only, without ordering (discounted) tickets for the same trip. This would explain why you can't choose the GA option for the Brig - Spiez leg. If you definitely want to arrange for seat reservations for this part of your journey (although they're not required and most of the times not really necessary), you could contact the SBB
and ask for information.
I hope it's clear now!
