I will need to travel a lot for work, but the days will vary. Is it possible to negotiate with NS for the Altijd Vrij pass, but for the specific days, instead of paying for the complete pass? This is especially important because the pass is very expensive and my job refunds only a smaller part of it. Would appreciate any help. Sadly, I cannot go for Traject op Maat, as my employer only pays for the parts of kilometers traveled.

I travel from Rotterdam to Schiphol to Amsterdam Zuid. 

Best,

Julia
