Hi Danhiel
Hello, thank you very much! I am traveling between Zurich and Budapest on October 23rd, 8.00-11.42 (EC163) Zurich-Innsbruck, 12.56-17.32 (RJ13477) Innsbruck-Vienna, 17.40-20.35 (RJ67) Wien-Bp. I bought my ticket at MÁV, but there are no seat tickets available for EC 163 yet (the other 2 trains are ok), and later MÁV will no longer allow it, because the Zurich-Innsbruck route is now completely international. The system does not indicate a replacement bus for this day yet. I will try to buy just the seat ticket on the SBB or ÖBB website later, I hope it will be valid with the MÁV ticket.
Kind regards,
Tibi
