NS Flex season ticket
With NS Flex season tickets, you can switch to 1st class any day up to 15 minutes after you check in. See what applies to your season ticket.
Credit balance season ticket
Do you have a credit balance subscription? You buy a class change on the day you want to use it. Check which situation applies to your season ticket.
Do you have a student travel card? If so, you cannot change your class at the moment.
Without a season ticket
If you do not have an NS season ticket but have a valid OV-chipkaart or OV-pas, you can also upgrade to 1st class.
You cannot change class with your debit card and will always travel in 2nd class.
NS-Business Card
You can also change class with an NS-Business Card. You can do this for one day in the NS app or at an NS Ticket Machine. The class change is only valid on NS trains.
Bear in mind that class changes do not appear on check-in poles, gates or the ticket machine. The class change is visible to the train conductor.
