The answer to this question depends not only on how the accident happened but where, who was involved in the accident, and whether there is a contract in place that is relevant to the accident.
For example, if a person is injured in an accident when they are travelling on a tour bus as part of a tour they booked through a cruise company, they may be able to claim compensation from the tour company and the cruise company, as well as potentially the individual(s) whose driving caused the accident.
A person who is injured at an airport, for example, may be able to claim compensation from the airline with which they were travelling, or the airport itself, depending on where in the airport the accident happened and when in the boarding/disembarking process the accident happened.
