Mehdorn Air in Nosedive - a very good summary of facts and commentary links around Deutsche Bahn AG's new pricing system. As a summary, one can say that Deutsche Bahn is engaging in considerable nonsense here; what is promised in advertising simply cannot be achieved by everyone based on the framework conditions alone.
For me, this definitely means fewer train trips, because on the one hand spontaneous journeys are no longer possible and on the other hand day trips have become more expensive for me (among other things because the large discounts require at least one night in between), and I therefore have to think about whether I really want to do this. Which of course annoys me - I've been a long-time BahnCard holder and actually really enjoy traveling by train. But when you're supposed to pay more for less service (like with the InterRegios that have been converted into ICs), that's where I draw the line. And these strange clauses, such as super saver discounts only being provided for 10% of seat capacity and no such prices being available once these are booked, that's bordering on false advertising.
And things like absolute train binding don't appeal to me much either - I like to change my mind and take a different train, and that option disappears with this system.
Sorry, Mr. Mehdorn, you've missed the mark. Grade: 6, sit down.
