The plaintiffs had booked tickets for a Lufthansa flight from Hamburg via Frankfurt to Miami and back from Los Angeles via Frankfurt to Hamburg. The ticket price was EUR 2.766,32 and according to the tariff, the ticket was non-refundable (except applicable taxes only). Because of a disease, the plaintiffs cancelled their tickets and claimed back the ticket price. Lufthansa only refunded taxes of EUR 133,56 each. The plaintiffs filed a law suit for the difference which was dismissed by the first instance court (AG Köln) and their appeal was dismissed as well.
