19.18.1 Airlines’ obligations to passengers under these Regulations shall not be limited or waived, notably by a derogation or restrictive clause in the contract of carriage.
19.18.2 If such a derogation or restrictive clause is applied in respect of a passenger, or if the passenger is not correctly informed of his rights and for that reason has accepted compensation which is inferior to that provided for in these Regulations, the passenger shall still be entitled to pursue any available remedies.
