Hi. I am trying to make seat reservations from Domodossola to Brig for Sep 3, 2023 but getting the error “The requested seat category is no longer available.” (for both 2nd and 1st class)
This train normally starts from Milan and goes to Brig, but the route from Milan to Domodossola is not running from Aug 21 and Sep 10. So, I am booking it from Domodossola to Brig.
I am not able to make this seat reservation for any of these dates. Reservation is possible for other dates when the full route of this train is active.
Are reservations not allowed for these dates OR are they sold out?
Appreciate any help.
