Swedish ferry company TT-Line runs several connections from Trelleborg in Sweden across the Baltic Sea. Until December 2026, you can get a decent discount on crossing between the Sweden and the German ports of Rostock or Travemünde by using this discount code:
TT-Lines promises the following discounts:
- 15% discount on oneway tickets
- 35% discount on roundtrips
Sadly, the discount only applies to the ticket price – and not to the Marpol & ETS surcharge, which is similar to airlines’ fuel surcharges. Because of this, the discount is smaller than the advertised 35% or 15%:

You can get a lower price per person by travelling in larger groups. The discount also applies to bookings with a car.
