The Twin City Liner, the ship connection between the capitals of Vienna and Bratislava, is now charging passengers a fuel surcharge of two euros per person and direction. This is based on the edge of a mailing with the sharp rise in purchase prices for diesel.

Apparently, this extra fee was "copied" in aviation, because numerous airlines have been charging so-called kerosene surcharges for many years. These are either openly identified as such or, as in the case of the Lufthansa Group, camouflaged as a so-called "international fee" so that, on request, they can say that no fuel surcharges will be charged at all. These were introduced by many airlines in the early 2000s when oil prices rose sharply for a short time. At that time it was promised that these would be abolished again if fuel prices fell. However, only a few airlines have remembered the promise.

Similar to aviation, the fuel surcharges for Twin City Liners are added to the ticket prices, making it noticeably more expensive for passengers. This is communicated in a single sentence at the very end of a media release that primarily deals with Advent travel between Vienna and Bratislava.

The Twin City Liner was originally developed to set up a fast connection between Vienna and Bratislava. However, the alternative to the car, train and long-distance bus was not accepted by the population as intended. The business model was therefore changed and positioned as a tourist and leisure ship. This is successful, because the joint venture between Wien Holding and Raiffeisenlandesbank NÖ-Wien has been on this route for many years. Occasionally they also offer special trips to Budapest.
