Yesterday (may 5th 2022) we bought 3 Interrail Continuous Passes for 1 month. Today (may 6th) we found out about a discount code which is valid from may 6th till may 10th. We didn’t know this discount code was coming up when we paid the full price for our tickets. I was wondering if we could change the previously booked tickets into ones using the discount code. Is it possible to get a refund for the amount of money we paid too much in comparison to the discount prices? It feels risky to have 6 tickets without knowing for sure we’ll be able to get a refund. Hope you can help us out!
