I am trying to book tickets from Athens to Kalambaka and return, and I can choose seats for Athens-Paleofarsalos and Kalambaka-Athens. But I have an issue when choosing the seats on the second train (from Paleofarsalos to Kalambaka). Is this fine? Or I may be fined on the train?
This is very confusing because also, the prices are different. It shows approximately 32 Euro for the trip Athens-Paleofarsalos-Kalambaka and 18 Euro Kalambaka-Athens, but at the very end (tickets with no reductions) the amount to be paid is about 38 Euro instead of 50 Euro.
Thank you very-very much!
