On the topic of Sparspreis Europa, is there any update on being able to buy these tickets for journeys beyond November 9?
No news so far. Statement on
DB Website:
Due to a system change at Eurostar, DB no longer has an interface to Eurostar. As a result, we can no longer offer saver and flexible fares for the entire journey from and to London from 9 November 2019. We are currently working on a more customer friendly solution with Eurostar. In the meantime, you can book your ticket via the international booking platform (link provided in the travel information on bahn.com).
The question is, if Eurostar is really interested in re-instating the offer. As far as I know, they get a fixed amount of money for each ticket the DB sells - no matter which price the DB charges the customer. Combine this, with the fact that oftentimes a ticket from Germany to London is sold cheaper than a mere EST Brussels->London ticket, this offer is not very attractive to EST.
I want to go to London in January. I have not decided yet, whether I will wait if something changes, or until tickets via Paris become available at SNCF or book a flight or ... On thing this is for sure: This whole mess does not encourage people to use the train.
