The Chamber of Labor criticized 37 clauses - 32 are inadmissible, including the check-in fee. The AK criticized 37 clauses in the general conditions of carriage of the airline Laudamotion and was largely right: the courts judged 32 to be inadmissible, for example because of non-transparent wording and inadmissible deadlines. The check-in fee is particularly noteworthy - it may not be charged if it is not clearly mentioned during the booking process. AK expert Gabriele Zgubic: "The ruling has an impact on the industry, but currently only applies to Laudamotion - proceedings against Ryanair and Wizz Air are still ongoing." No mention of check-in fee Accordingly, passengers had to pay a fee of 55 euros per flight and person for checking in at the airport. The clause is unusual, disadvantageous and inadmissible due to its amount, said the AK in the press release. Nor was it pointed out during the booking process. Get your check-in fee back - here's how: You can now claim back the check-in fee from Laudamotion if you were not made aware of it during booking and you had to pay the fee at the airport. The AK advised consumers to only pay the check-in fee until the legal matter has been resolved and to request a refund and to request the refund in writing from the airline.
