(1) Where the price increase reserved in the contract in accordance with section 651f (1) exceeds eight per cent of the price of the package, the organiser may not unilaterally effect it. However, the organiser may offer a corresponding price increase to the traveller and demand that the traveller
1. accept the offer of a price increase or
2. declare their rescission of the contract
within a period of time specified by the organiser, which must be reasonable.
Sentence 2 applies accordingly to amendments of the contract other than price increases if the organiser is able to procure the package due to a circumstance that arose after conclusion of the contract only by way of significantly modifying one of the essential features of the travel services (Article 250 section 3 no. 1 of the Introductory Act to the Civil Code (Einführungsgesetz zum Bürgerlichen Gesetzbuche)) or only by deviating from special requirements made by the traveller that have become part of the contract’s content. The offer of a price increase cannot be made later than 20 days prior start of the package; the offer of some other amendments of the contract may not be made after the start of the package.
(2) In their offer of a price increase or of some other amendment of the contract under subsection (1), the organiser also may offer to the traveller the option of participating in a different package (alternative package). The organiser is to inform the traveller in accordance with Article 250 section 10 of the Introductory Act to the Civil Code. Upon expiry of the period of time specified by the organiser, the offer of a price increase or of some other amendment of the contract is considered accepted.
(3) Where the traveller rescinds the contract, section 651h subsection (1) sentence 2 and subsection (5) apply accordingly; the traveller’s claims under section 651i (3) no. 7 remain unaffected. Where the traveller accepts the offer of an amendment of the contract or of participation in an alternative package and where that package is not, at a minimum, of a nature equivalent to that of the originally owed package, section 651m applies accordingly; if it is of an equivalent nature but entails lower costs for the organiser, then section 651m (2) is to be applied accordingly with regard to the amount of the difference.
