Hello,
Can anyone explain to me how does the supplement required in IC Trains in the Netherlands work? I’ve been reading some answers to similar questions related to this topic here but I’m still in doubt if it’s due to going to the airport that I need to pay the supplement. In the DiscoverEU portal says that I need to buy it so I can open the gates at the Brussels Airport at my arrival from Amsterdam Centraal and that it is available at train stations and online. How much does this supplement cost and do I really need to pay for it? I have a FLEX pass btw.
And do this IC trains get too full? I’m quite stressed about this journey because it’s my last connection (I have a flight later that day) and I don’t want to be surprised there. Where can I really buy this supplement and is this connection really frequent?
Thank you so much!
