The SUPPLemt for passholder is 30€ to BRU and I think 33 or 35 to AMS-so thats not much of a difference. And you could save a passday for another easier to arrange interesting trip.

It MAY also be quite possible that seats to AMS-as even though this city (where I worked for many yrs-long ago) wants to bar more tourists-both by charging sky-high tourist taxes and by active discouraging news items- are sold (there is just a tiny quota) and you could try only to BRU and use the hourly yellow, a little slower BeNeLux trains from there-you wont be the only 1 to do so.

Pass holder seats are available:

This is via Belgian railways. Pass cover number needed, booking fee 4€ per order.

You can also book by phone via SNCF (press #85 for English). No pass cover number needed, no booking fee, but the call is not free (it's a normal phone number though, not a premium one).

I just tried to book from b-europe and it’s only valied for paper format passes, mine’s digital. What else can I do?

@Magdalena could you help with a pass cover number?

Otherwise, like I wrote above, you can call SNCF. Reservations will still be delivered via e-mail.
