I know this is an old thread and post but maybe someone can answer my question.
I am trying to book from the Frankfurt Airport to Budapest Keliti. It is a Railjet Express with no train changes required. I can buy a 1st class ticket on Bahn.de and reserve a 1st class seat but not a Business seat. Oebb.at will not sell this ticket but will allow me to reserve a Business seat for the normal 15 euro. Will it work if I buy my 1st class ticket on Bahn and pay the normal 15 euro supplement on Oebb.
Thanks
