I have an Interrail global pass in mobile format, shown in the Rail Planner app.
One point that surprised me is that there are 3 outbound/inbound days in total although classic rules tells that there are only two trips allowed in the country of residence in total.
I enquired the Interrail support directly and they told me that the residents of my country are allowed a third outbound or inbound day, with no additional explanation on eventual limitations, and just to enjoy being able to take advantage of that new condition.
This is confusing, as a popup in the app tells that the extra day may be present in case it takes a long time to travel out of / back into my country of residence.
The pass has a long duration. I have a plan to split my travel using this pass in two sessions with returning home in-between. For the additional inbound and outbound trips not covered by the pass, I would simply buy point-to-point tickets from my home to the border station.
In this situation, can I use the third day as an actual additional outbound travel day, saving the cost of one domestic ticket? The answer given by Interrail support would let me think that this is permitted, but I am still in doubt about it. I really want to avoid being considered in fraud in the middle of my travel.
