FIP coupons on IC train - Zurich - Basel - reservations/supplements needed?

[43094]

Hello

I have FIP coupons and am planning to undertake a journey on an IC train - Zurich - Basel on 7 November (the train then continues on to Amsterdam).

The following morning, I'm intending doing the journey in reverse.

Would anyone be able to advise if a) FIP coupons are valid on this and if so, b) what reservations / supplements I'd need to accompany them please?

Thanks in anticipation!

FIP coupons are valid on this service without reservation or supplement for internal Swiss journeys.
