The rules that govern travel time guarantees differ from one service operator to another. You must contact the service operator concerned to find out which rules apply in the event of a delay.
Acquaint yourself with the rules that apply before choosing another means of transport to reach your destination. A refund of your extra travel expenses often requires that certain conditions are fulfilled, and sometimes you will only get a partial refund of your expenses. A maximum expense refund amount also applies.
If you have been delayed and you wish to contact the service operator to check whether you are eligible for a refund, make sure that you have detailed information about your planned journey and the actual delay involved.
