By Train from London (United Kingdom) to Wien / Vienna (Austria) - Option 3: Depart on Monday and Thursday evenings and make one connection in Brussels

Book early and save: Yes

Online bookings open:  Between 138 and 190 days ahead of the travel date

The price shown below is the standard, most heavily discounted, one way Standard Class price - however, Eurostar frequently offers special fare/deals promotions, so the price you see on the home page of the Eurostar website MAY be cheaper.

Also note that on the Eurostar booking site, it only uses the English name of the main station in the Belgian capital - so enter 'Brussels Midi' into its search.

............................................................

Also worth knowing is that when travelling by Eurostar you can choose between three classes of service, but it isn't possible to select different types of ticket.
So there isn't an option to pay a higher price for a less restrictive type of ticket, which can be refunded etc - all tickets are non-refundable if you subsequently need to cancel your travel plans.

If you book Standard or Standard Premier tickets, you can exchange them if need be, to an alternative departure on your booked route - but you will need to pay an admin fee of £30 for Standard Class tickets, £40 for Standard Premier tickets PLUS the price difference with the new ticket you will be booking - and prices will probably have increased since making your original booking.

Business Premier tickets are less restrictive, they can't be refunded, but they can be exchanged to alternative departures without paying the admin fee, or the price difference.
Business Premier tickets can also be exchanged to the alternative journey options with a connection in Bruxelles - but if you booked Standard or Standard Premier tickets, they can only be exchanged to alternative direct trains.

Using rail passes:

Rail pass users must reserve before boarding this train.

You can now book rail pass reservations without paying booking fees on the OBB website (OBB operates these trains
Though the process for doing so isn't particularly obvious, hence this step-by-step guide.

Or you can avoid the booking fees by arranging the reservations when you arrive in Austtria, by purchasing them at a Reisezentrum travel desk, which you will find in any hauptbahnhof.

Though it's best to do this when you first arrive in Austria, the later you leave booking your accommodation, the more likely it is that your preferences will be sold out.
