For occasional ticket
They are valid for a set of zones counting around the zone where you started your journey (the place where you made your 1st validation) and up to the limit of zones acquired (Z2 if there are 2 zones, Z3 if there are 3 zones, …). All occasional tickets are valid for a minimum of 2 zones.
Allows you to travel for a certain period of time depending on the number of zones acquired (Z2 – 2 rings of zones, Z3 – 3 rings of zones, …).
If a Blue Andante card is topped up with 1 Z2 single ticket and the customer needs to use a Z3, that same ticket can be topped up. The last to be topped up is the 1st to be used. In this case, when validating, the customer will use the Z3 and keep the Z2 balance.
