Hi, I’m planning my trip through Europe e and I hope you could help me with some doubts I have.

I will go from Italy to Monaco and then to Berlin. After this I would like to move to the Iberian Peninsula. I would like to use a flight to get from Berlin to Barcelona and then use the rest of my pass over there.

However I cannot understand if this would create problems in the travel plan in the Rail planner app (I will use an online pass), considering that there would be a "gap" in the journey.
Would someone who has not exclusively used the pass to get around during their trip be able to help me with this?

Thanks
