Once you receive your digital tickets, print them in A4 format and keep the printed copy with you, as validation is only accepted in printed form. To benefit from discounts on attractions and other services, present your printed ticket to each discount partner before you request the discount.
Public transport tickets need to be validated before your first trip in the city. Look for validation machines at the airport, city railway platforms, buses, and trams for easy access.
The 72-hour tickets are valid for exactly 72 hours from the time of validation. For example, if you validate your 72-hour card at 8:30 am on Monday, it will be valid until 8:29 am on the following Thursday.
Validity
The validity of online tickets is based on the date (and time, for the 48-hour and 72-hour variants) specified on the ticket. The 4-day, 5-day, and 6-day tickets expire at midnight on the final day of their validity.
