Plus pass - how to pay for additional reservations when all your credits are used up?

We’re trying out the plus pass for the first time, travelling from Switzerland to the UK.

The TGV Lyria and the Eurostar both require 1 credit each, so our return trip will be a total of 4 credits. Because we only have 3, we’ll need to pay for one reservation (like with a regular pass), as stated on the Interrail website info about the plus pass.

But I can’t figure out how to pay for the additional reservation- does anyone know? When I try to reserve through Interrail I get a message saying “ Not enough free reservations left!” but no option to pay instead.

Do I need to use another provider, or is there a way around this within the Interrail reservations booking system?

Thanks for your help…

(And I agree with many others on other threads, it would be great if the number of credits included in the plus pass is increased! Otherwise I think we will not use it again.)

If you don't have any credits left, then you pay for a regular reservation.

The Plus pass reservations can only be done via Interrail. Any other reservations are best done elsewhere.

For all pass reservations, use this page as a guide:

TGV and Eurostar are best booked on raileurope.com.

Thank you ​@rvdborgt Seat61 is great. But I don’t see anything specifically about using the plus pass and how to pay for reservations after you have used up all your credits. Did I miss that?
