Buying ticket on Mav (Budapest to Vienna)

When you reach the page with the schedules , there is a field which requires date of travel , birthdate and number of passengers and a few other items ; THEN , click on tickets and prices . On the next page that appears there will be a price shown on the left , click it . NEXT page shows a description of the ticket , click where it says OPEN . Next page will show a list of choices click in the circle to the right to choose , then on TICKET to THE CART . You should be able to go on from there .

Steven, I did that you described, but it only shows options with railjet, not all options like in initial page, as I wanted at 19:10, at this time is not available to buy, I don't know if that one is only sold at station and not online, any idea????

My best explanation is that this is a regional train to Kelenfold and a change there to a night train which proceeds to Zurich . Since it is a regional train , advance booking is not possible . Sorry , it's my considered judgement , at this point .

I could see the final destination is Zurich and it goes through Kelenföld, but there isn't any change of train on schedule (19:10) between Budapest and Vienna according to the timetable.

True , as I consider this , a more appropriate answer is that since this is a night sleeper ( about ten hours from Vienna to Zurich ) the regional carriages may be uncoupled from the train somewhere along the way . Even if not , and no change of train , this is still essentially a regional leg and an EN leg . My experience in other countries is that generally , regional trains only sell tickets a relatively short time in advance ( I had a similar experience in Italy several years ago - I was able to buy Venice to Milan way in advance for a discounted price , but had to wait until I got to Venice to buy the last ( regionale ) leg which was Milan to Stresa ( about an hour ) . That ticket was only available about eight days ahead . That being said , you could probably buy the segment you need when you get to Budapest , or more simply , use one of the Railjets and go a bit earlier .

Thanks Steven, that makes sense.
I'm afraid to leave to buy when I arrive there and it's not possible to reserve seats anymore (as I will be there only for 2 days), also my second issue to buy online on earlier schedule is that I got error (invalid Master card data), but I inserted data more than once to certify that was all right and also I already bought on DB BAhn and OBB without problems, so I don't know if that is an issue on validation of MAv website.

This may sound obvious but double check the date format and double check with your bank to make sure they aren't the problem.

I can't guarantee anything but the odds are very, very good that you can easily get the tickets when you arrive. You might also consider calling MAV. I have called them with questions in the past and they were very helpful. Maybe your hotel can help? A last resort is a company called

Helpers.hu

I sent an email to Mav, but I didn't receive any answer about problem with credit card. Anyway, I tryed 2 more times to buy online with Master card and got the same error, then I decided to try with Visa card, then it worked, finally :-), so something going wrong with master cards I believe.

Well done! Congratulations!
Now you need to plan your week in Budapest.

Glad it worked out . James will have a lot of great information that will make your time in Budapest a real joy , it's a great place .
