Article XII : arrangements for additional services
The Carrier, within the scope of a Contract of Carriage and subject to applicable law, may agree to provide the Passenger with ancillary services via third parties. In this case the Carrier will incur no liability towards Passengers, except in the event of wilful or serious negligence on the Carrier’s part.
If the Carrier provides surface transport services, other Conditions of Carriage and, in particular, other liability systems may apply to such surface transport. The Conditions of Carriage and the liability systems are available, upon request, from the Carrier or from the Carrier providing the surface transport services, as applicable.
