There are no discounted 1st class tickets available from Budapest to Vienna (only in the opposite direction!), which is a bit of a pain, but not a great problem because the trains are new Railjets, and 2nd class is perfectly OK.
Hmm, the Austrian Railways website shows a first-class discounted ticket price from Budapest to Vienna, but when one continues in the booking process, you are right, a message pops up noting that it can't be bought on the internet. A previous window mentions buying the ticket through the railway's call center or by email, but I've never tried that. Have you, or do you have any information on those options, particularly from another country to Austria? (And should I have read your post to mean that
on the internet there are "no discounted 1st class tickets available..."?) The German railway, by the way, will also book the ticket for you through their call center, but not on the internet - and with no indication of whether they can apply the discounted fare.
