I have bought a return ticket from Vienna Airport to Budapest and I need to change trains at Wien Hauptbahnhof to take the onward train to Budapest. The train to Wien Hauptbahnhof leaves the airport at 1503 hrs and arrives at Wien Hauptbahnhof at 1518 hrs. My train to Budapest is at 1542 hrs. I received an update from OBB mentioning there are some works going on and connections cannot be guaranteed.
I was wondering if I can take an earlier train to Wien Hauptbahnhof from the airport on the same ticker or do I need another ticket. I tried to go through the T&Cs but couldn't find anything in English, all in German it seems.
Has anybody tried this or do I need to buy a new ticket ?
NB:- I have a reservation on both legs of the journey and a specific train number is mentioned on the ticket too.
