Directive (EU) 2015/2302 of the European Parliament and of the CouncilShow full title

Article 10 Alteration of the price

1. Member States shall ensure that after the conclusion of the package travel contract, prices may be increased only if the contract expressly reserves that possibility and states that the traveller is entitled to price reduction under paragraph 4. In that event the package travel contract shall state how price revisions are to be calculated. Price increases shall be possible exclusively as a direct consequence of changes in:

(a) the price of the carriage of passengers resulting from the cost of fuel or other power sources;

(b) the level of taxes or fees on the travel services included in the contract imposed by third parties not directly involved in the performance of the package, including tourist taxes, landing taxes or embarkation or disembarkation fees at ports and airports; or

(c) the exchange rates relevant to the package.

2. If the price increase referred to in paragraph 1 of this Article exceeds 8 % of the total price of the package, Article 11(2) to (5) shall apply.

3. Irrespective of its extent, a price increase shall be possible only if the organiser notifies the traveller clearly and comprehensibly of it with a justification for that increase and a calculation, on a durable medium at the latest 20 days before the start of the package.

4. If the package travel contract stipulates the possibility of price increases, the traveller shall have the right to a price reduction corresponding to any decrease in the costs referred to in points (a), (b) and (c) of paragraph 1 that occurs after the conclusion of the contract before the start of the package.

5. In the event of a price decrease, the organiser shall have the right to deduct actual administrative expenses from the refund owed to the traveller. At the traveller's request, the organiser shall provide proof of those administrative expenses.
