Here is my situation:
I bought my Global Pass for 4 days for the 2nd class seats.
I planned out my trip in the app with all of the trains that I would need. None of the trains show available seats and are all sold out.
Is it possible to pay an extra fee for 1st class tickets to still get on the trains with my 2nd class ticket? I don’t mind changing my pass for a 1st class pass.
This is my planning:
Amsterdam to Paris on the 4th of August
Paris to Barcelona on the 7th of August
Barcelona to Paris on the 13th of August
Paris to Amsterdam on the 14the of August
Thank you for your help in advance!
