Canceling a Travel Plan: Planning Manager 
Use
In the overview of travel plans in the planning manager you can cancel entire travel plans. When you do so, all travel services booked in the plan are canceled at the same time. Travel plans must be canceled before they can be deleted.
You can cancel car rental and flight reservations at any time, as long as no ticket has been issued. Depending on the provider, cancelation fees may be charged if a ticket has been issued. The responsible travel agency can give information about these fees. (See also
